Lingerie Friday: Thread Tales

stretch mesh panties

Has it really been two weeks? We’re still in the throes of moving… boxes and boxes everywhere in both places. In the midst we’ve both managed to preserve tiny corners of creative spaces for our own sanity, so I packed up everything but my sewing machine and a few lingerie projects. I’ve been tweaking another new pattern lately which gave me an excuse to play with my latest fabric love, sheer stretch mesh. The mesh I’ve been using is so delicate and soft, and of course I had to spend an evening dyeing it, too! First minty green and then a pale gold-yellow…

But it is a little picky about needles and stitch lengths. And even thread. So today I wanted to share a couple of my new favorite threads for lingerie and especially for these more delicate fabrics. Both are delicate but don’t snap under tension. I love how tailors are unequivocal about their buttonhole threads, and it was inevitable that I’d be that way about lingerie thread, too!

Gutermann A192 (or Mara 150) Fine Thread

Gutermann thread A192

Funny enough, it was the Cutter & Tailor forum where I first read about this as a good thread for fine shirtmaking. It is also recommended for silks and lingerie. It’s impossible to capture in photos the difference between these and their all-purpose brother above, but this is a remarkably fine but strong thread. It just sinks into fabrics and makes the topstitching on bra cup seams less bulky.

I’ve only found A192 in tailoring supply shops but it’s well worth the hunt! Mine came from from Oshman Brothers in NYC and according to their gracious owner, Gutermann is phasing out their A192 threads to a new thread called Mara 150, so you might find this thread under either name. I got one of each, since Oshman’s stock is still mostly the older type, but both are very fine, strong threads. I placed such a tiny order from them, but Mr. Oshman sent me a long email explaining the transition and the technology difference behind the new threads (core-spun polyester with microfiber core, etc.) If you want to understand thread, you have a willing teacher!

Wooly Nylon or Wooly Polyester

wooly nylon thread

These are much easier to find in your local store, but I was missing out on a good secret! In knits and especially in underwear, wooly threads make the softest, airiest seams against the skin.

woolly nylon seam

Until about a year ago I was in the dark about wooly nylon. And the first time I shopped for some I accidentally confused it with blindstitch thread. Oops, big difference! I ended up with a bunch of cones of plasticky thread I doubt I’ll ever use.

Wooly threads are kind of springy and spongy, and as you can see look like little cloud-strings. The most common type is wooly nylon but there is also wooly polyester.

wooly nylon serging

I don’t have tons of room for serger threads, so I have a bit of a color strategy. There are a few neutrals that seem to blend with everything. Ivory, dark grey, red, nude and a light grey have been great basics for most of my lingerie. The ivory blends into most pale warm colors. The light grey blends into most pale cool colors. The dark grey is good for blacks and very dark colors.

When serging, it’s easiest to use wooly thread in the loopers and regular serger thread in the needle. And the best way to get those spongy threads through the loopers is by tying the them onto the tails of your previous looper threads, then pulling them through. I learned that one the hard way…

Do you have any favorite threads?

Happy weekend! Now back to those boxes…

Adjusting Your Bra Band (With Math!)

zebra lace and lycra

I’m making a new lingerie set using this funky yellow zebra lace from Merckwaerdigh. I find animal prints hard to resist and this one is so soft, feminine and subtle. But to make a bra from this set I have to make some pattern adjustments to the band. The matching lycra is a super stretchy 4-way lycra/spandex fabric, and if you have ever tried to make bras with new band fabrics you probably figured out that no two band fabrics fit alike!

If you were to take apart a few of your RTW bras and detach the elastic, you’d notice the bands are all different lengths. This doesn’t necessarily mean they are different band sizes, just that they were drafted with the negative ease particularly needed for that fabric. Unfortunately, most commercial patterns aren’t always clear on the stretch percent or type of stretch for which they were drafted, probably to allow for the widest interpretation possible.

There is a way to get around all this without worrying about sizes. I like to adjust my band pieces for each bra using just a little bit of math. It’s easy math, I promise!

{ONE} If you have already made a bra from your pattern, put on your bra and measure from the side seam of your bra around your back to the other side seam:

measuring for band

The line of the tape should be level with your underbust along the elastic hem. Try to hold the tape firmly–you want a firm number.

*If your pattern doesn’t have a side seam, you’ll need to measure from the side of your cup where the underwire is all the way around to the other side.

{TWO} Find the width of your bra back closure, with the closure on the loosest hook. Subtract this number from the back measurement you just took in step 1.

measuring hook & eye closure

My Back Measurement 15 7/8″ – Closure Width 2 1/8 = 13.75″

Divide this number in half. This is the length of your bra band piece with no negative ease. Mine would be 6 7/8″. Now you need to adjust it for the stretch of your fabric.

{THREE} Find out the stretch percent of your fabric. I first find the direction in which the fabric stretches the most, and take a length of about 5″ or 12cm and stretch it to its maximum along a ruler.

lycra at rest

My lycra stretches from 5 to almost 10″, which is 100% stretch. The calculation: (5″ stretched / 5″ original length) x 100 = 100%.

lycra stretch percent

Using your stretch percent, you can now make some logical adjustments to your band. Obviously the more a fabric stretches the shorter you want your band to be.

{FOUR} For band fabrics, I have found that reducing length by 3% for every 10% of stretch generally works. For example, if your fabric has a 75% stretch, then multiply 3 x 7.5 to get the stretch reduction of 22.5%. My lycra stretches almost 100%, so I multiply 3 x 10 to get a stretch reduction of 30%.

I take my measurement from step 2, and multiply it by 70%. (Reducing by 30%.)

6.875 x .70 = 4.8″

That is how long I want my new band piece to be along the hemline, from the stitching line of the side seam to the line where the back closure is sewn. My current band piece is 5.4″, which was a good fit in a heavier powernet.

band original width

To shorten this piece, I slash down the middle and overlap. until the new hem length reaches 4.8″. Then I retrace the band and smooth out the lines. Voila–a new band piece!

slash and spread band piece

*Note that it’s important to take these measurements between the seam lines and not the edge of the seam allowance. Seam allowance doesn’t count toward length!

Of course math isn’t the whole story and there are other factors which will influence the fit, including how tightly you pull your elastic while sewing. But I have found this to be a good starting point so I don’t end up with too-loose bands. As always testing is always your best friend!

Polka Dotty Lingerie

dotted knit foam bra

Over the summer, Katherine of Blooms Endless Summer and I exchanged a few lingerie patterns we had drafted. It’s been wonderful finding online sewing friends with whom to chat about patternmaking experiments, and we both share a genuine love of pattern analysis. She was gracious to share the pattern she drafted for her Daisy bra, which I had some time to finish over the weekend.

A few moons ago I bought this comfy soft dotted rayon jersey for some Ladyshorts and, well, a lady has to have a bra to match!

dotted lingerie set

Katherine drafted her bra using Patternmaking for Underwear Design by Kristina Shin, a book I’ve since bought and used as a reference in some of my own drafting. Because Katherine’s a different size than me and the book does not demonstrate drafting in measurements other than a 34B, I used my own bra blocks to adjust and grade the size and fit. In her post about this bra (linked at the top), she also included an illustration showing how she adjusted the original draft to fit her particular shape. This may help some who have have less volume on top and need to visualize what cup pieces could look like. As so many of you have figured out in the sew-along, bra fit is such a subtle thing. We all have different shapes, or a shape we’d like to be!

In this bra, the lining is the structural layer, a three-piece foam cup which allows for the shaping and support. The outside is only a two-piece cup meant to be made from lycra, or possibly a jersey as I used, to shape smoothly over the foam.

In these type of bras, the foam is usually joined by a zig-zag or triple zig-zag, then covered with seam tape. I have made them both with and without covering tape and it doesn’t seem to affect the feel or strength. But of course I like neat finishes! For this one I used a soft 1/4″ cotton twill tape and stitched a straight stitch on either side.

To stabilize the cradle and bridge I used a fusible knit interfacing. On top of that I stitched a lightweight tricot lining to the bridge so I could clean finish the clever little “v”. I like this part of the design, which follows the neckline of the cups to a point. I have some space to work with in my bridge so little style changes like this one are easy to incorporate.

You might be wondering, do I wear all these bras I make? Yes! Yes, all of them, and I’m nearly at the point where I have phased out store bras except for a couple of investment lingerie pieces which I splurge on for my own luxury. My first couple of handmade bras fit fairly well and while they may have not been my favorite fabrics, style or fit they still work when everything else is in the laundry! Another thing to remember is that no bra lasts forever. Elastic can age very quickly with two- or three-times-a-week wear. And it particularly does in a climate like mine, where sheer body heat breaks down highly elastic clothing. I have to replace my workout clothes once or twice a year! I’m very particular about handwashing my delicates. I lightly wash after two wears to rinse out body oils, I don’t wring, I use a very mild detergent made for lingerie in small doses. But even with that care, some bras don’t last more than a year. I too have been guilty of wearing bras way past their point of usefulness!

This is one of a few foam style bras I have made for some comfy whatever days and since I work from home I have more of those than I care to admit!

Bra-making Sew Along: Grand Finale!

Friends, it has been a wonderful ride and it’s time for a wrap-up. I love season finales. You know, the kind of plot ending where all the characters–even the ones who mysteriously morphed into into their evil twin two seasons ago–return to the screen for one final blow-out episode. Plot loopholes be darned, closure is good for the heart.

My finished bras!

pale green lace bra by Amy

This bra fits me like a dream. If you’ve been following along you’ve probably picked up on all my little (and not so little) alterations. I altered my cup to a vertical seam. I also used shorter underwires, lowered the neckline about 3/8″, and widened the straps in front–more of a demi style. My bra is made from mostly stash materials that I dyed to match the pale grey-green lace. (I’m really into blushing mints right now!)

pale peach longline bra by Amy

My friend’s bra is made from Elan 645 using a bra kit from Fabric Depot Co. I made some alterations to her cup seams to fit for a softer look and lengthened her band a bit–both around the body and lengthwise for a longline bra.

Sewy Rebecca by Michelle Sews

Michelle joins me in a passion for collecting bra patterns. She started out with Danglez DB3 but decided she’d be better off trying Sewy’s Rebecca bra (above). Rebecca is a fantastic pattern, especially for larger cups. Michelle also informed us that Bra-makers Supply was about to release a new pattern called Shelley–as of today it’s available here. For those Sewy Rebecca fans and others who need the option of a side cup piece and multi-seaming–this one’s gonna be a big hit. I just know it. Hop over to Michelle’s blog to see a she drafted a Shelley-type bra from her Pin-up Classic pattern.

Kazz went on a bra-making spree, y’all. Here’s her post about this set. I think I’m going to have to pull out all my black lace now because wow. Wow. She took the “Hack Your Bra” idea to heart and is just killing her Elan 645 pattern with all kinds of styles–bustiers, longlines

Did you make a bra and would you like to share? Let us know in the comments! Understandably, I got behind on all my blog reading, so I may have missed you if you blogged about it. If you were a secret sew-alonger you can email me, too. I’d love to hear about your project and how it went.

Over at the Flickr group we had quite the fitting expedition. I’m even in the process of custom-drafting a bra for someone! I really want to thank Norma Loehr and her generosity in answering so many of our fitting questions. And there were many!

It was such an honor to host this sew-along, chat with many of you, and I hope it inspired y’all to keep on at it! You caught the lingerie bug, didn’t you…

Bra-making Sew-Along: Elastic, Channeling and Finish!

Time for all the finishing bits! Okay, so there are a lot of finishing bits, so get on your elastic because this post is going to be picture heavy.

Band Elastic

If you’ve made other lingerie goodies with picot elastic, you’re probably familiar with how this is done. The first side is sewn with the fuzzy side up and a regular zig-zag, getting very close to the picots.

sewing band elastic

band elastic zig-zag

If you want to cut your elastic to measure, a good general rule of thumb is to cut a length about 95% of the seamline of your hem. I like to “feel” it in as I am sewing–just something that happens from experience with sewing elastic. How much tension I put on the elastic depends on the elastic quality. (Update Jan 2015: See this post for some tips on sewing elastic and how how much tension to use. Since this sew along, I have reduced the amount of tension I use in elastics.)

I flip and on the reverse, stitch the elastic with a 3-step zig-zag. You could also stitch from the elastic side. I prefer doing it fabric side up so I can keep the puckers away:

band elastic 3-step zig-zag

I set my 3-step at 4.8 width and 1.2 length. (I wrote all my bra stitch lengths on a little post-it note on my machine so I don’t have to look it up every time I make a bra or panties!) The 3-step is just security to keep stitches from popping. But if your machine doesn’t have a 3-step, you can use a regular zig-zag and experiment with smaller stitch lengths.


I know the channeling gets finicky. Readers have asked me about how I did this on previous bras so I thought I’d show in pictures!

I usually attach the channeling first, before putting in the band elastic. It’s easier to make that first pass without the elastic in the way but it adds another step and I wanted to make this simple visually.

First I lay down the channeling so its seam is right on top of the cup seam and start stitching right on that seam. To make sure I don’t accidentally stitch into the cup, I hold the channeling in my right hand, lift it up, re-arrange it as I go–while using my left hand to guide the cup seam. This has worked really well for me.

stitching channeling to seam

I stitch all the way to the top of the front but stop and backtack about 1/2″ before I get to the end of the underarm seam. It’s good to leave a little extra hanging off each end. This helps to finish the channel neatly later on.

After stitching the channeling I grade the seams if there are a lot of layers–and there’s quite a few here!

channeling seams

Before I do anything else, I close off the channeling in the front. Since the seams are still free and not topstitched down, I grab the top of the channeling with the cup seam allowances and fold everything else out of the way:

closing front of channeling

Then I stitch a really tight zigzag that almost looks like a bar-tack. Whatever it is, it needs to be secure!

closing top of channeling

The closure is invisible from the outside. (On my friend’s bra–I forgot to snap a pic of my mine!)

closed channeling bridge view

Time for the topstitching! I switch back to my straight stitch foot (ok, I just found out my machine calls this a “patchwork foot”). I turn the bra over and arrange the cup seams and channeling so they are folded under toward the band. If you’ve ever done an understitch on a facing, this first part is just like that. I hold the fabric on both sides a little bit taut, and start topstitching about 1/8″ away from the edge of the cup seam.

edgestitching channeling

I have to keep feeling to make sure this stitch is going into the channeling. If you sewed your first pass with the channeling seam on top of the cup seam, this shouldn’t be a problem.

Then I do another line of topstitching with the first line of stitching lined up right under my foot edge. This is about 6mm on my foot. Don’t forget to stop your topstitching 1/2″ away from the underarm so you can fold it out of the way for your elastic.

channeling outside topstitching

Underarm Elastic

Now’s the time to put in my underarm elastic. I do my first pass just like the band elastic with the fuzzy side up. I use a bit less tension in this elastic than I did with the band.

When sewing in the elastic I have to fold away the channeling–that’s why I stopped stitching it 1/2″ away:

applying underarm elastic

Before folding over the underarm elastic I put in my underwires, sliding them in from the open underarm sides toward the front.

inserting underwires

At this point you need to decide whether you want your channeling to be closed on top of the elastic or folded into it. I’ve done both and it really depends on how thick the channeling is!

Right below my thumb is where I’m going to close the channeling with another “bar-tack” again:

finishing channeling

I need enough room to fold down my elastic and stitch another 3-step–this is where that wire play I talked about comes in handy. I can’t tell you how many times my underwire has reached right to the fold of the elastic–a recipe for underwire and needle disaster!

After closing off the channel and stitching down the underarm elastic, this is what it looks from the outside:

channeling backtack

Almost there! Now I attach my straps and finish off with my hook and eye. Every pattern has a different width at the end of the band for a hook & eye attachment. You usually need to adjust that to fit your particular hook and eye width before you sew in your strap elastic:

attaching hook & eye

That’s it! My bras are done and I’ll be back Monday with photos and some roundup questions. Happy sewing weekend everyone!

How to Sew Bra Straps

How to sew bra straps | Cloth Habit

Sewing bra straps might seem ridiculously simple but when I first started out sewing bras, I could never figure out which end went where through the slider. Maybe it’s because I’m lefthanded–the visuals always look backwards. So today’s tutorial may be for the lefties out there!

A couple of notes before we begin:

Straps are constructed the same way whether the adjusters are in front or back of a bra. If putting them in the back of the bra, you’ll need to sew a strip of strap elastic to the back band and leave a little bit hanging off in order to create a loop around the ring. If putting the adjusters in the front of the bra, you’ll need to create a loop for the ring at the top of the cup. This is done in one of two ways:

  • If your cup design has a strap extension (examples of that here and in the Watson pattern), you can loop this around the ring and stitch to secure.
  • If your cup design does not have a strap extension, you will secure the ring using extra underarm elastic. Here is an example of how I did that, while using a bit of firm ribbon inside the elastic to stabilize the loop.

Step 1: Cut Your Strap Elastic

I like to cut my straps about 18 inches for insurance. How long each strap needs to be depends on two things: the length of your shoulder to bust and the design of your bra. Most women need about 15-18″ for a full elastic strap.

Step 2: Attach the Slider

Thread one end of your elastic through the slider. Fold it over so that the wrong (plush) sides are facing each other and stitch a secure seam. I use a small straight stitch (about 1.0-1.5 length), and stitch back and forth.

How to sew bra straps | Cloth Habit

Step 3: Finish Threading The Elastic

Slide a ring over the unstitched end of the elastic (which you can see in the above photo). Then bring the unstitched end up toward the slider, so that the plush sides are facing each other.

Now thread your elastic up and through the slider like so:

How to sew bra straps | Cloth Habit

Keep pulling the unstitched end until you end up with a loop.

How to sew bra straps | Cloth Habit

The finished loop should be about 1-2 inches but no more than that. Remember that you will be tightening your bra straps as the elastic ages, which creates a longer loop.

The straps are sewn at the end but it’s always nice to have them pre-assembled.

As you can see from the top photo I’m making my straps using half elastic and half spaghetti straps using silk charmeuse. I had to come up with this fun design since I forgot to take my own advice and buy extra strap elastic! The Bra-makers notions kit I used includes about 10 inches of strap elastic per strap (since their patterns are designed for a half-fabric strap). I’ve assembled the elastic portion of my straps identically to the nude straps, but the ring and the adjusters will be in the back. The spaghetti straps will go up and over my shoulder meeting the ring at the top of my back.

How do you like to do your straps? Do you favor the adjustment in the front or back?

(p.s. For rouleau/spaghetti ties like mine, here is a very clever tutorial at 3 Hours Past.)

Bra-making Sew Along: Sewing the Cups

finished bra cups

Alrighty, how’s it going y’all? I’d love to hear. I know some are still fitting and some of you have made two or 10 bras by now! Me, I’ve made better friends with my Canon than I ever thought possible…

Before I break out the sewing machine, a couple of things that I’ve been using on my bras.

A straight stitch foot. I use my foot as the seam guide–the distance between the needle and the edge of this foot is exactly 1/4″.

straight stitch foot

Of course, don’t forget to switch to your zig-zag foot when sewing your elastic. There’s a big Ask How I Know. Which is why I have extra needles…

I use a stretch needle, size 11/75. This has been perfect for elastic and lycra, but also seems to work best on all the tricot-type fabrics. For lace I sometimes go to a very small needle. I’m always experimenting!

assemble the cups

How you proceed on your cups depends on whether you are fully lining your cup, or just lining one part (like the bottom)–or not lining at all.

On my friend’s bra, I’m using lace only on the top cup, as an overlay on the regular bra fabric (in this case, simplex from a bra kit). I want the cross cup seam allowances to be totally hidden inside the seam, so I stitched the three layers together with the lower cup sandwiched in between.

lace cup with an upper lining

lace upper cup with lining

“sandwich” turned right side out, before topstitching…

On my bra, the outer cup is entirely lace and the lining is interfaced silk charmeuse, so I constructed the two layers separately:

separate lace cup and lining

To flatten the seams, I turned the seam allowances over to one side and edgestitched onto the allowances, just a tiny width away from the seam.

sewn cup after edgestitching

Your pattern may have instructions to press open seams and topstitch on both sides. Or topstitch the seam allowances together to one side. This is really up to your preference and how thick your material is! Most often, I like to edgestitch which flattens the seam enough for me.

So when I was first starting to make bras, I struggled with rippled seams across the cup. Oh the dreaded rippled seam in knits! Since seam rippling is usually caused by one or the other layers stretching too much, here are a few things to try:

  • If your machine has this ability, try lightening the foot pressure.
  • As you are sewing, try not to pull or stretch the fabric in any way–let your hands simply be a guide.
  • Try sewing without pins! When sewing two different curves together, or concave and convex curves, pinning pulls one layer into the direction of the other which can cause the length to stretch. It takes some practice at first, easing off a pin here and there. Eventually I went cold turkey pin-free! Which has improved my curves sewing and feel for fabric handling.

finish the top of cups

At this point I want to finish the top of my cup! If you are sewing a continuous trim that finishes both the cup and bridge, you’ll wait till you’ve sewn your cups into the band.

Both of my cups have two layers on top–the scalloped lace and non-stretch lining. To finish the edge of the lining, I tried a technique based on one of my fave strapless bras. I sewed a strip of sheer tricot along the outside top of the cup with a 1/4″ seam allowance.

sewing tricot facing strip

Then I turned, and top-stitched this down along the inside. I could have done this in reverse, too–which would totally hide the seam. It’s pretty soft as it is. The tricot is cut along the least stretch so it stabilizes things a bit.

topstitching tricot facing strip

To keep the lace from shifting around on top, I tacked it down in three spots with a small back-and-forth zig zag stitch (almost like a bartack!). I saw this done in an Elle Macpherson bra and liked its invisibility.

tacking lace to upper cup

Since my bra has a vertical seam, I tacked down the lace to the lining with a couple of straight stitches right at their joining seams.

tacking lace to vertical seam

After you’ve finished the top of your cup, you can baste the layers together around remaining edges, so that the cup will be treated like one piece. I do this just inside the seam allowance–it’ll all get hidden underneath channeling and elastic! When basting stretch lace, it sometimes wants to stretch past the lining, as you can see in the above photo. It’s just the nature of stretch–I try to keep the excess toward the bottom of the cup and just trim it off!

other cup finishes

There are loads of different ways to finish the top of your cup! I’m always experimenting.

top cup finishes

l to r: foldover elastic as a binding, decollete or clear elastic along the bottom of scallops, picot or piping elastic, lace and lining layers sewn right sides together for an invisible finish (which I wrote about here).

Bra-making Sew Along: Cutting

cutting bra pattern

The time has come to cut our bras!

By now if you’ve been making tester bras or alterations you probably know your bra pattern inside and out. And that’s a good thing! Understanding a pattern makes sewing so much easier, don’t you think?

Before I start cutting, I like to double-check a few things on my pattern:

Check the cradle seam to make sure it has enough length for your chosen underwire. The cradle seam should be the length of your underwire PLUS 5/8″ (or 16 mm).

underwire length & cradle length

This extra length gives your wire about 8mm wiggle room on each end (called “wire play” in bra drafting). If you have ever tried to sew a bra without that allowance, you might know the pain of breaking a needle because you hit the wire while sewing down elastic (CHECK!) or your wires have strained and popped the channeling seam (CHECK!). If you end up needing more length you can add a bit more to one side or the other, or both. Don’t forget you’ll have to add this new length to the corresponding cup seams.

The distance between the cradle and elastic seam lines should be at least the width of your band elastic (otherwise you’ll be sewing elastic into your cup!).

bra band elastic width

After that, it never hurts to walk your seams in your cups and cradle to make sure the actual stitching lines match–especially if you’ve been making alterations!

lining or interfacing

You may have already figured this out in some of your tester bra experiments, but there are many ways to stabilize a cup and remove some of the stretch. You can either sew a lining underneath your main cup fabric, interface it, or both!

For my bra, I’m cutting my entire cup and cradle out of lace and lining it with silk. I really wanted to try silk on this bra!

For stability, I interfaced the silk with a fusible knit. You can see I blockfused my fabric before cutting. I’m a fan of blockfusing, especially when it comes to small pieces that get finicky and time-consuming to interface.

interfacing cup & cradle fabric

For my friend’s bra, I’m using simplex from a bra kit with lace on the top cup. I’m new to this fabric and debated over whether to fuse it–it’s stable but has a lot of drape which I suspect will make the cup drop a little. She’s definitely going to get another bra after this anyway!

The cradle or bridge area should not stretch at all horizontally. Again, I don’t think a lining is necessary for simplex but I went ahead and cut one out of sheer tricot.


stretch directions

All of your pieces should have a line which indications the stretch direction. Bra fabrics can have their greatest stretch in either direction, so test your fabric to be sure! Even the more stable bra fabrics have some mechanical stretch.

Regardless of the pattern, I usually cut my upper cups with the neckline running parallel to the stretch. Unless I’m stabilizing it, I don’t really want this piece stretching up and down as it will stress the strap, nor on the bias which tends to permanently stretch.

stretch direction for cutting cup pieces

stretch direction cradle

If you are using lace, 4-way stretch fabric or a print that you want to run in a particular direction, it can be lined or interfaced to stabilize it.

cutting lace

There are many ways to use lace in a bra and I really love working out lace puzzles!

When cutting the lace, it is helpful to have your seam lines marked in your cup and cradle pattern. I usually cut one side of the cup first to center the motifs. I make sure the stitching line of the upper cup is lined up with the lowest point of the scallops:

centering lace scallops

I also try to line up the piece so that the stitching line that meets the bridge hits a bottom point of a scallop. When the bridge and cup are sewn together it will match up nicely:

lining up scallops with stitching lines

I usually cut one side first, then flip over the cup pieces to cut another mirroring side. It just so happened I have a 2nd pattern piece that I can flip:

cutting matching side on lace

But often when I’m cutting a bra, I simply cut the first piece, flip it to find a matching side and carefully run a rotary cutter around it.

cutting matching side of lace

Some galloon laces have mirroring motifs, some don’t. If not, I try to get close so the motifs are similar on both sides.

All cut!

cutting notes

I mentioned this before, but I like to transfer my master pattern to something like card stock or in this case oak tag (same paper as manila file folders). I’ve even scanned my pattern so I can print it out multiple times onto weightier paper. (No more re-tracing!) This not only preserves the pattern but gives me an edge on which to trace around with tailor’s chalk directly onto the fabric:

I use a small weight (or just my hands!), chalk around the pattern, then cut away the chalk lines. I like doing it this way because it gives me a really accurate cut, while pinning sometimes distorts the fabric (especially lycra and lace). This is just a cutting method that I’ve picked up from pattern-makers–it takes me all of 5 minutes to cut a bra pattern!

Bra-making Sew Along: Vertical Seam Variation

(Hack Your Bra Part 2!)

I love a diagonally-seamed cup because it is especially pretty in lace, with an unbroken line of scallops across the top. But it’s been fun to play around with seam directions for different style and shape options.

vertically-seamed cups

In today’s tutorial, I’ll share two pattern variations you can make to your cup: 1. adding an additional seam to your lower cup for a 3-piece pattern and 2. changing the entire cup to a vertically-seamed one. I’m using the 2nd variation for my own bra which you will see in action next week!

A tip for these alterations: The main seams in a cup should cross over your bust point. In some patterns, there is a notch at that point–usually right at the apex–if not, find it on your bra and mark it on your pattern so you know where it is. After your alterations, walk your pieces and double check that the lengths of the actual seam lines match.

Adding a Seam to the Lower Cup

ONE: For a second seam in the lower cup, mark a line going from your bust point down to the bottom seam line.

It doesn’t matter where the line ends at the bottom so feel free to experiment! In this example, I’m dividing the lower cup into two relatively equal pieces, which will result in a seam that runs perpendicular to the main seam.

TWO: Cut the pattern piece along the lines and trace your two new pieces. Draw in a smooth, even curve connecting the top and bottom seamlines. The curve should be fairly subtle.

THREE: That’s it–your new pieces! Don’t forget to walk the seamlines and add 1/4″ allowances to the new seam.

Vertical Seam Alteration

For this alteration, first mark where you want your seam to start and end. A vertical seam doesn’t have to be straight up and down–you could slant inwards or outwards. I found my starting points by marking these positions on a previous bra. It just so happens that my pattern–Pin-up Girls Classic–has a notch right at the center bottom, which is usually where a straight vertical seam starts.

ONE: Mark the bust point of your pattern.

TWO: On both pieces, mark in lines on the top and bottom cups, going from the desired starting point of your new seam to the bust point. I rotated the bottom cup in this example so I could draw a straight line down the two.

THREE: Split these pieces apart on the lines. You should now have four pieces total.

FOUR: Line up the top and bottom pieces along the sides until the seamline along the sides of the cup form smooth curves.

vertical seam variation #4

The cross-cup seamlines will match each other for a short distance, but will not come together at the bust point. Trace off the these new inner and outer pieces.

FIVE: Depending on your pattern style and where the apex is, one side may have smaller “dart” than the other. In this case, the outer cup has the smaller dart, so draw your new seam line on this side first. Draw in a smooth curve connecting the two upper and lower pieces close to the bust point.

vertical seam variation #5

On the inner cup, draw another curve of equal length. Because the “dart” on this side is so wide, the curve will not go around the apex. (You need to take some out from that “dart”, if that makes sense!) You can use a measuring tape to find the right curve length.

ETA: The flatter these curves, the less length (and volume) the cup will have. In your fitting, experiment with them to find the shape you like. If you’d like to pull things in more, you can experiment with making the inner curve slightly flatter than the outer curve–a good tool to use in shaping!

SIX: Smooth out all the new seam lines, mark your bust point notch, and add seam allowances.

In the above illustration I’m also smoothing off that strap extension from my pattern, because I’m not going to use a fabric strap.

There ya go–a totally new cup!

I hope these are clear, so let me know if you have any questions!

Have a beautiful weekend, all. And get ready to start the engines–on Monday we’ll finally get to sewing and I’ll start with some cutting and layout tips. See you then!

Bra-making Sew Along: Hack Your Bra #1

I have to admit that this part of the sew-along is the part I was most excited about! I love the process of thinking about shapes, of sitting down with paper and rulers (or lately, Illustrator) and drawing new design ideas. I know pattern-making can seem intimidating but bras are such a great way to jump in and exercise your secret hacker. It all involves so little paper and fabric!

So in the spirit of my Lingerie Fridays, I want to share some of my favorite bras with you along with some ideas on how to generate them from your base pattern.

band style

How about a longline? (Cool examples: Freya, Fortnight…) I love these for style but they’ve got a function, too. The wider the band, the more supportive it is. And I think they look pretty sweet underneath thinner tops. I’ve made this alteration to a few of my bras:

You can lengthen the band straight from center front, side seam and back, as the lines in red demonstrate. The longer these lines get, the narrower the band will at the bottom so if you need more width you might have to try lengthening at a different angle (lines in blue).

strap style

How about fabric or lace straps?

Again, style and function–the less elastic the strap, the longer it lasts. This beautiful Stella bra uses a scalloped lace and a silk satin strap in the front.

The back design is really up to you. I love having options in back strap designs. It’s easy to change your pattern back and forth from a u-back to a camisole back.

changing from u-back to camisole back

In a camisole style, the elastic works best if it is tacked down to both the top and bottom of the band.

bridge style

You can do a lot of funky things with the bridge, too. If you are using longer underwires but want create a little plunge effect, you can try using separator wires, as in this lovely Huit bra.

These wires come in all sorts of shapes. The construction would be a fun puzzle, as you either need channeling or a tunnel to insert the wire. I may try this on my next bra and I’ll let ya know how it turns out!

demi cups

If a demi style appeals to you, you can always take some of the height out of your cup and bridge. This is an Elle Macpherson demi bra with similar seams as some of our patterns. To do this you’ll need shorter or plunge wires, or clip your own.

I love playing the game of “How Did They Do That?” and often do a little investigation in the stores (it must look funny, as I look inside the seams–the things you do when you sew!). So I hope this gives you some fun ideas as you continue your bra-making adventure.

Tomorrow I’ll be taking the pattern-hacking a bit further with a tutorial on adding vertical seams to your cups. After bit of a breather over the weekend, on Monday we can finally get down to the business of sewing our bras. Woo!
