My machine just does not like cotton thread. She is a prissy. She only likes the Glide. I put some on, made a couple of minor adjustments and she is quilting like a dream. Go figure! My dealer says she will buy all of my cotton thread back because that is what her machine likes. I was sure glad about that. No need to have it here if I can't use it. Now, what to do with some of my other "I don't ever use things". Thank you all for all the suggestions. I watched the videos and they didn't really help me cause I don't have the magna bobbins. Couldn't keep my bobbin in long enough to do the test. I guess what works for one doesn't always work for the other. I would have to buy a tempermental machine.
