There is supposed to be a gap between the foot and the sandwich. This allows the sandwich to move freely.
Yes, the presser foots needs to be lowered, I have forgot and ended up with a mess on the back of my quilt :oops: :lol:
Bring your bobbin thread up to the top before you start quilting. Hold onto both threads while taking your first stitch or two :D:D:D
Can you post a picture of what the bobbin thread is doing? Sometimes it is easier to diagnose a problem if we can see it :D:D:D
Are the loose loops all over the back? Or just when you are starting out?
