How do I sew stretchy material without it bunching up?
You can also sew the stretchy fabric on top of a “stabilizer” of some kind, then remove the stabilizer afterward. There are various types, some even dissolve in water… just ask at a fabric store for the possibilities. Be aware though that if you don’t build some stretch –extra thread– into the stitching on a stretchy fabric, you *can’t* stretch it afterward or the thread will break. That’s why a “stretch stitch” is used, or you can do the same thing by using a bit of zigzag stitch (fairly long) instead of a straight stitch –while stretching the fabric slightly as you sew– that’s a commonly used way of sewing seams of sweatshirts, t-shirt material, etc. Good luck!
