I have the same set up as you do, if I want to do the whole block I have to advance and back up alot. I do mostly all over meandering. I'm not good at ruler work yet, but I practice it alot. It takes alot of time moving back and forth but it's worth it. When I get over half way thru the quilt and my throat space gets too small, I tack my sides and the end of quilt down and put a few rows of basting, then turn the quilt. Then I start were if left off and quilt to the end. Then the quilt is all on the belly bar.
