Hi Everybody. I have a dilemma. I'm trying to teach myself free motion quilting now that I bought a new Pfaff that has feed dogs that drop. I was playing with scrap fabric and it was working fine, then it starts to act up (or maybe it was the machine operator). I start getting long stitches, 3-4 inches long, and then the top thread breaks. After this happened about 4 times I gave up. The bobbin thread doesn't look too bad, but I think I'm doing something wrong with the top because it keeps breaking. Can someone, anyone help me???
