I have to say that I practiced and practiced FMQ on my little machine, and I sucked at it. But when I got a frame and mid-arm, it is a whole different story. I find it so much easier to move the carriage over the quilt, and it's a completely different thing for me. If you have LA in a local shop that you can rent for a time, you ought to try it. Although I must warn you it can be addictive.
Good luck.
