How do you sew stretchy fabric without bunching?

How do you keep stretch fabric from puckering?

Solution. Reduce the tension applied to the thread while it is being wound onto the lock stitch bobbin. Set the needle thread tension to be as light as possible while achieving a balanced stitch at the same time. This will reduce the amount of puckering while the thread is stretched and improve the sewability.

What is the best stitch for sewing stretchy fabric?

The best stitches to use for sewing stretch fabrics are:

  1. Narrow zigzag: opt for a very narrow setting with the zigzag, with the stitch length equal to the stitch width.
  2. Overedge stitch: a speciality stitch that locks over the edge of the fabric so it stitches and finishes a seam in one pass.

What causes bunching when sewing?

Your Thread Tails Are Too Short

If the thread tails that come out of your bobbin are shorter than two inches, they may get sucked into your sewing machine when you begin to sew. This can cause thread bunching underneath your fabric.

What tension should I use for thin fabric?
