Thanks everyone. Left the C&C in the bobbin since I had just put fresh thread on and used the Essential on the top, same weight. No problems. Ended up just doing it in a grid to get it done. Will play with it more tomorrow. Thank you for all your input. I really appreciate it.

when you are finished with sewing and you go to change the thread do you pull the thread back to the spool? You should always cut the thread and pullit from the needle out. It works like flossing you teeth. Also worng needle, is it a quilting needle. They have a longer shaft to allow for the depth of the top ad bottonm fab and bat. Could also be tension.

Always cut thread and pull it through, although I grit my teeth every time because of the waste. I am using a quilting needle and tried the 3 sizes. Adjusted the tension a tiny bit with every try. It worked fine once I went with the essentials thread on top. The bobbin didn't seem to be a problem. I did make sure they were the same weight. Thanks for all the suggestions.

good luck

Yes, I have had that same experience. Sometimes it's just that the thread is not so good. I have also hit weak spots in thread that break and break, so I pull off a few feet of it and then start again and it's fine. I think all the brands have some of that.
