If you are getting bobbin thread bunching under your fabric, your bobbin might be inserted backward. Some sewing machines require your thread to go clockwise in your bobbin case, and some require it to go counterclockwise.
Why is my sewing machine 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.
Why does my thread keep bunching at the needle?
If the thread is too tight in the needle, or too loose, the stitching may cause problems. … If your needle and thread ratio is not proportionate, you run the risk of bunching your thread under or over the fabric.
