I am new to quilting. I finished my quilt top and it turned out great. I wanted to do some freemotion stippling on the outer perimeter and watched video after video and even read a few books. I started practicing. EVERY time the same thing. The top thread ends up with a huge nest on the underside of the quilt. Even at best I have a large loose loop of the top thread on the bottom. I have adjusted the tension in small amounts from +3 to -3 and NOTHING has helped. I have left the feed dogs up (have a supreme slider in place so it wont move the fabric) because one instructor said this might help and it made no difference. I have a singer 7426. Does anyone else this model or a singer that can help me shed some light on a solution here. There is no way to adjust anything on here but thread tension, stitch length and needle placement. I have tried matching threads in top and bottom, using poly thread on top and bottom. I just have no idea what I am doing so wrong. PLEASE HELP ME! Till now my experience with quilting has been such a positive one. But I am so stuck. There is a DVD that helps but I am not going to buy one that will simply tell me the same things I have already been told in the utube instructions and then have the added frustration of having paid money I dont have and STILL be stuck.
