I have been quilting with my milli for 8 years and just recently started having a problem with the machine pulling the top thread to the back, and getting caught up in the hook and bobbin area. I would have to cut the thread and then pick out the thread that was in the hook assembly. I thought it must be a timing issue, so I redid the timing. It got worse! Now the top thread goes to the back, and makes a big knotted mess, and then continues on as if nothing happened. Then occasionally, there will be a big loopy stitch. It doesn't actually skip a stitch, just leaves a loop, then continues on with normal stitches for a while. When I pulled the last quilt off the frame, it had these "knots" about every foot or so of quilting. When I cut the knots out, it takes some of the stitches out. I would post photos, but the lady really wants her quilt so I already trimmed all the mess. (I should mention I was using King Tut thread. Normally, I use Glide) Any ideas?
