Hi girls, I am a first time post-er. I have a problem! I was sewing a strips for a quilt last night(fleece) and I got 1/2 through and my machine when nuts-o. At the bottome of the material the thread would tangle into a huge mess, and if I didn't catch it, it would get all jammed in the machine. I read the manual, and checked the bobbin (used a new one, used new thread, cleaned everything, and adjusted the tension. So I'm at a loss. Any help will greatly be appreciated! Oh and here's a pic of some shirts I screened for my sister, my mother and I. The heart is a tattoo my sister and I have on our behinds!
