Thank you all so very much! All good advice. I will try the top tension. It only happens maybe 4-5 times on a small quilt. I will also work on the springs. Those may very well be the problem. I have had my machine since 2008 and have never needed to change any springs and no issues except for wheels. Hope they are easy to do. My machine has been a dream to use. I have probably only done about 250-300 quilts. Thanks again everyone!!
