If you’ve been sewing for a long time, you’ve probably never thought twice about how to wind a bobbin. But did you know that if you wind it at high speed the thread can actually stretch out and affect your stitch quality?!

All purpose polyester thread has a bit of stretch which allows it to withstand some pressure when putting that garment on. If you wind your bobbin at high speed the thread is pulled faster and stretches, causing it to wind unevenly. When you sew, the bobbin thread has a chance to relax in the seam making it look wavy or have small loops on the underside which can be confused as a tension problem when really it’s a bobbin winding problem.
