I mostly use monofilament thread because of the bobbin and/or top thread will pop up. I really want to be able to use cotton thread but I'm afraid I'll run the quilt top. What do you do when you want to do an all over design on a multi colored top? I'm so used to using the monofilament, I've gotten spoiled to not thinking about it. I would appreciate some advise.(oh yes, I have adjust my tension, both top and bottom)
