Ok, got another question. I am practicing FMQ with some small square sandwiches and when I lower my darning foot it appears that there's not much room for the quilt to move freely. I brought one for my specific machine. I kept it up instead of lowering to see if I could still quilt but not so successful. Also I noticed on the back of the quilt instead of tight flat stitches theres loose loops around the thread not sure what I'm doing there. I set at zero, tension at about 4. Any suggestions? Thank you.
