Iam trying different things also, to learn how to machine quilt. I learned that the pressure on the pressure foot needs to be adjusted. That usually is round and on top of the machine and you have to use your screw driver that came with the machine to loosen it. Also, I have tried with a walking foot and a darning foot. I seem to have the same results. I will be watching this topic page with great interest as I also want to know how. Lots of luck
