Ok, help! I am doing free motion quilting and the thread broke twice. once I was using poly on poly thread. by mistake actually. it shredded and got caught up inside my machine. was using a quilting needle, changed to a top stitch 90/12 or 90/14 one with cotton on cotton. I now have half of Santa's beard done but it shredded again. any suggestions on needle size. I thought a larger eye would help too but evidently not.
