Thread breaking with FMQ
My thread keep breaking while FMQ. At the break, it is shredded. I'm using Sulky 30 wt in top and bobbin. 90/14 top stitch needle. What could be wrong? I cleaned the machine and it's a new needle. Also what's the rule about the real big stitches vs. the tiny ones? I know it has to do with the speed of the hands and/or foot pedal. TIA
