Tips For Sewing With Spandex Elastane and Lycra

It’s swimsuit season! In our June/July issue, we talked to sewists who dared to make their own swimsuits. Many of them loved the experience and the feeling of accomplishment they got from completing an intimidating project.

Why is sewing swimsuits so scary? Personally, I think there are a number of reasons. There’s the challenge of getting the fit just right, of course — a badly-fitting swimsuit has the potential for worse consequences than many garments — but I think a lot of it is that the techniques are not the same ones we use in our normal sewing. Sewing knits can be challenging enough; where do you even start with something like spandex?

It turns out that, just like with any fabric, there are a few tricks to know, but once you know them, it’s not hard to sew with an unfamiliar fabric. Here are some suggestions, courtesy of Rhonda Buss, who did our Soma Swimsuit Sew Along in 2016.

  • Use a needle designed for stretch fabrics, such as a ballpoint, jersey or stretch needle. If you’re sewing metallic fabric and it’s giving you trouble, try a metallic needle.
  • Start the project with a new needle to avoid any existing burrs snagging the fabric.
  • The selvage on spandex can be wavy, puckered or distorted, so be sure to cut it off before you begin cutting.
  • Sew using a serger if available. If not, use a stretch stitch or a narrow zigzag stitch.
  • Use wooly nylon thread in the serger loopers or in the bobbin. This adds extra stretch to the stitches.
  • Make sure to test stitch on scrap fabric to perfect the machine tension before beginning construction.
  • If the fabric gets caught in the throat plate, change to a straight-stitch plate if possible (but not if you’re using a zigzag stitch for construction!)
  • Remember to cut the fabric so the direction of greatest stretch is going around the body.
  • If prewashing the fabric (and when laundering after construction), don’t dry the fabric in the dryer, as the heat can break down the elastic in the fabric. Air-dry instead.

    Hi Janice,
    If the leg openings are encased elastic, try making a small opening in the casing and shorten the elastic, by cutting it to the length needed for your desired fit PLUS about 1 inch to overlap and restitch the elastic, then close up the casing again.
    Good luck !

  2. Hi Kate
    Omg, Never really thought about sowing like your own swimsuit especially with lycra. Do you do this full time or is it just a hobby? Would love to know how you start doing this. What tools can you purchase for people on a low budget?

    I just bought a swimsuit, it fits really well except the leg openings, they are really big. How do I make them fit.
