soccertxi, does the needle size also affect thread breakage with cotton? I am having the same problems and wondered if maybe its the flannel quilt, I've changed needles, cleaned everything twice, shut here down and started over and am still getting a breakage about every 18 inches. I've been quilting a long time, and have never had so much trouble with one quilt. About ready to put it in the orphan projects box, but my DGS would miss out since his brother gets one that I had no trouble with
