When I FMQ, using monafilment on top and bottom, extra top thread is often pulled to the underside causing a small "nest", breaking the thread, skipping a few stitches and then picking up again, stitching normally.
I use a thread stand and have wrapped the top thread around the tension guide used to wind bobbins. It has helped me some, but not completely.
Question: What is Mode 2?
Hope to read about solutions to our problems. Suzanne
