Little thread blobs on back.
Every so often I get a thread blob on the back. Is it tension issue? I've tried adjusting, cleaning, changing needles. Everything I can think of. It doesn't do it on a sample. Just the real quilt. ????
I have one of those bohemoth machines that I'd need a truck to get in for servicing.
Anyone have any ideas.
Oh, it only does it when quilting,, not piecing.
