Rachelcb80, I know this reply might be 2 years too late - but I found you thread when I was having the exact same problem as you were. I have a Bernina 830e and a bsr foot it would quilt perfectly on a quilt sandwich - but when I tried to do FMQ on my twin size quilt - it would keep skipping. It was driving me crazy - I really mean crazy - I tried everything - then I remembered reading somewhere to try a 90/14 stretch needle or ball point needle and I finally tried it and the amazing thing is that it worked. I now can actually FMQ and not have it skipping all the time.
