I finally have my Grace Inspira frame & Juki 2010 set up, have my practice quilt loaded & I'm ready to go! I've done a few loops & my top thread breaks. Tried again & again it broke. I'm using the SureStitch regulator, Connecting Threads 100% cotton thread both top & bottom & a new needle. The machine is threaded properly & the tensions are correct. What am I doing wrong? Should I be using a different thread? I'd appreciate any & all suggestions.
