I have my machine back. There was a piece of thread caught in the cutter against the outside wall of the machine. How it got there is a mystery. The fact that it was blue thread, and I haven't sewn with blue thread since August, a mystery. Supposedly a lot of adjustments were made. We will see what happens. I have a lot of quilting to do between now and Christmas, just like every other quilter, so I am hoping for no more issues.
