How do you stabilize a bias seam?

Why is my thread bunching underneath?

A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.

Ensure you opt for the right size of needle for your fabric. Use stitches that will hold the stretch of the fabric – the stitches need to stretch with the fabric, so they don’t pucker and break. If you must sew with a straight stitch, then hold the material taut, but don’t pull it.
