Cashs_mom, I have a second spool so I'll change out and see if that helps. I tried stitching for 2 minutes and stopping for a minute, checking the thread and then continuing for another 2 minutes and it seemed to help a little but at the end it snapped anyway. Even when I was just basting. Thought maybe I had the quilt too tight as that causes thread to snap also but I'll try your idea on Saturday as tomorrow is shopping day with my sister so a day off from quilting altogether.
