I have been machine quilting for about 10 years. on the weekends I can quilt a double to queen on Sat., if I just quilt and don't do housework or laundry also, about 6-8 hours with breaks. I have made a queen size start to finish in a few days, as I am aging, I try to make them faster. I want to use up most of my huge fabric stash before I check out.
