I had my Tin Lizzie serviced about 2 months ago and now it is doing the same thing- the thread gets so tight in the tension disc that it won't go through so the thread breaks every few inches. Any ideas from other frustrate Tin Lizzie owners? I have changed needles, checked the bobbin tension, threaded and rethreaded - looked on line and no help. Seems that there is always something that needs adjusting. The Lizzie stitch is not working again so I'm doing the manual stitch. I have 3 quilts ready to quilt - so frustrated!!!!!!!!!!!!!!!!!!!!!!
