I have a long-standing love affair with sewing underwear, as shown from my first post on making underwear (6 years ago!) and the several more I’ve posted specifically since then. The little mini-series with my underwear free pattern and the how-tos of sewing them are the posts with the most traffic here on the blog.
I’ve made many more pairs of underwear than has made it on the blog (really, they all look the same after a while!), but some experiments have turned out so well I want to share them. I’ll call this the fourth installment in the underwear series, and this is on inserting lace in a pair of stretch fabric undies. Note! I use a length of stretch lace ribbon, not a piece of cut lace fabric. Just so we’re all on the same page!
1. Take your front (or back) piece and mark where you want the lace to go. I like mine on a slight angle, almost parallel with the side seam but quite as steep. Mark a line on the outside of where you want your ribbon to be. I mark not the center, but to the side so I can more easily line up the lace ribbon. If you know where you want the center of the lace to be, just make another line *half the width of the lace* towards the side seam.
Cut the length of lace with a bit of overhang – this makes it easier during the sewing process. I actually don’t cut off the excess until after I’ve sewed across it however I’m finishing the leg hole openings and waist seam. I find this makes for a sturdier construction.
2. Use thread that matches the lace on top, and a bobbin thread that matches your fabric color. Sew down the ribbon with a zig-zag stitch on each edge. If the scallops are deep and pronounced, you might want to follow them exactly. Otherwise, just make sure you securely fasten the lace to the fabric on both sides. I sewed with a width of 3 mm, and stitchlength of just over 1 mm – at least the numbers on my sewing machine was 3 and 1! If the stitchlength is too short you’ll get wavy seams, so adjust to a longer stitchlength if that happens.
3. If you want appliquéd lace and like the look of what’s going on, stop here! Assemble the rest of the undies as you would normally – check out my tutorial on sewing underwear for help with that. Continue with the steps if you want to insert a piece of lace, meaning you’ll see the skin through the lace when you wear the underwear.
3. Give the stitched on lace ribbon a good press. The elastic is made of synthetic materials, so you might want to use a presscloth. From the wrong side, cut down the middle of the fabric only, between the two rows of stitches. Cut carefully – you don’t want to accidentally cut your lace at this point!
4. Press the excess fabric between the two rows of stitches to either side.
5. Stitch another row of zig-zag stitches right on top of the first one, catching the folded layer of fabric underneath. If your lace is 1″ wide or more, you could also position the second row of zig-zag stitches to the outside of the lace, sewing only through two layers of fabric and avoiding the lace altogether. This makes for a little less bulk and secures more of the fabric excess on the inside.
These pairs are actually made from a swapped tunic I shortened to a t-shirt. On the one I kept the finishing super simple and just overlocked all outer edges. For the waist I threaded a thin round elastic through the overlocked loops on the back and tied a knot to secure. For the second pair I went on lace elastic overload and just used it everywhere! For the leg hole openings I overlapped most of the elastic with the fabric, and did two rows of zig-zag stitches to secure it down, while for the waist I overlapped just about 1/3 of the elastic, and sewed just the one row of stitches.
