Another thing to try if you're FMQ on a domestic - look up Leah Day's video on how she modifies her hopping foot. It made all the difference in the world for me. I went from months of ugly practice sandwiches to quilting that I'm willing to show off (not perfect, but darned good) in a matter of days once I modified my foot. Leah shows you how to make the foot not hop but glide over the fabric, and also to open the toe to improve visibility.
