Anyone have any suggestions? I have three projects to finish quilting before Monday, and my machine has decided to start acting up. It started breaking thread, then skipping stitches. I have totally re-threaded the machine, cleaned everything I can clean, and replaced the needle twice with new needles. I am free-motion quilting 100% cotton top and backing and Hobbs 80-20 batting. Sulky 100% cotton thread. ( I have used 2+ spools of the same thread on this quilt already.) Suggestions please!!!!
