I was getting low on my all cotton thread, so I picked up a spool of Coats all cotton at JoAnn's. I was sewing some patches last night and it was so frustrating that it would constantly break. I was trying to figure out why all of a sudden I had threads breaking. I was thinking I should get on here to ask why it would all of a sudden start. I've been piecing for YBR for a couple of weeks and hadn't had tread breaking until last night. I think I found my answer here.
