I'm almost done FMQing my first, full-sized quilt on a vintage Singer 403A. It's been a total headache for me. Some of the stitching looks OK, some looks terrible. I can't tell you how many feet of stitching I've had to tear out. I've watched Leah's videos and at this point, I think I've had a good amount of practicing, but I still have, "bad stitching sessions." I'm with Sue, if you have any more tips, please share.
