I'm new to longarm quilting with my Juki 2010. Just loaded a practice quilt on the frame. My top thread keeps breaking. I'm using Connecting Threads 100% cotton thread on top and bottom. The machine is threaded properly and the tensions are fine. Needle is OK. I'm using a SureStitch regulator. Is there a different thread I should use or does anyone have a suggestion? Thanks, I need all the help I can get.
