I think I have tried everything I can think of: new needle, different threads. Some times putting in a larger needle 16 works..
Do you have any other suggestions?? I have had it in the shop for this problem, but no help..
Thanks for joining us. Bette
Do you have a zig zag stitch on that machine? It could be that the hook timing is not centered for a zig zag machine, or you have a burr on the rotary hook.
