I recently free motioned my first quilt on a Brother 1500S. The quilt was 96 by 96 and I had no problem moving it through the nine inch harp. I think I could easily do a larger quilt. As others have said, a large table to the left and back of the machine is invaluable. I also use gloves, forgot and left them off, could not figure out why the process became so hard. Duh! This time I only meandered but I hope to get more creative. Love the process!
