This is what is on my quilt frame, and has been for almost 2 weeks now. I'm quilting it in a very simple design, so it should have been finished already. But the top thread keeps shredding and breaking. That means that I have to unpick the stitches to a point where the threads are long enough to tie off. Then re-thread, and start again. It's very frustrating. The tension looks good and I have tried everything I can think of to reduce the breakage. It may be just one of those thread/batting/design combos that is difficult.
