I've taken it off the frame and used it as a regular sewing machine, but I have the same problems. (I wasn't sure if it was a problem with the machine or the quilt/frame.) I'm about ready to give up, but I see that nearly everyone here that has this machine loves it. I love it too, until I feed a new piece of fabric in and it clumps/breaks the thread. Any ideas?
