Your tension is too tight in either the top, bottom, or both. Check you manual to see how to adjust it.

If your tension is OK, your thread could be old (this is so common when thread is old). Try new thread on a scrap of the same fabric and see if this resolves the issue.

OR your bobbin thread could be wound too tight this can cause bunching. Try a bobbin that still has thread that you know works.

OR your bobbin could be improperly seated (take it out and make sure it clicks when you seat it back in.

OR your bobbin release screw (if you have one) is too tight. One of my machines, I think it is my Kenmore, the bobbin has a screw that controls the bobbin tension and if it gets too tight, it causes the issue like you are describing.

Post back what helps!!

You do not say if it is bunching on top or underneath and that will make a difference in what is causing the problem.

• You have been given good suggestions to try so I'm not sure that I can add anything but check this out.

• "Anytime the sewing machine thread is bunching up, or bird nesting, on the top of your fabric, the culprit has something to do with your bobbin."
• "The reasons that thread can bunch up underneath your fabric have all to do with your needle tension."

• This is an excellent article that has suggestions for vintage and newer machines (and you did not give the name or age of your machine).

• If you are still having trouble then just Google your question..
