I have a Pfaff 360 and have been trying to FMQ but the results are getting worse with every try. I successfully quilted one top and was excited that it worked. I then did a second with minimal trouble. The tread jammed in the bobbin a quite a few times towards the end of my quilting but nothing I couldn't handle. Then I tried my third quilt and I can't seem to get anywhere with it. The thread not only jams in the bobbin but the top thread is breaking and now I just broke my needle. I have tried different thread, making new bobbins, changing the needle, adjusting the tension etc. I have tried to lloosen the upper tension but that only made my needle break. It seems that as I sew the thread in the tension disks gets very tight to where I can't even pull on the tread easily. Also my zigzag stitch is unusable - it bunches up completely but the straight stitch looks good. I can't tell you how discouraged I am. I finally have a good feel for the motion and the petal control and feel pretty confident about my FMQ skills but my machine is acting like a naughty child. If you have one of these machines and have done FMQ with it PLEASE help me. My next option is to give up on this machine and try my mother-in-laws Bernina Activa.
