I'm currently taking the Leah Day Craftsy class FMQ Sampler. The best thing I've learned so far is that you should come to a slow stop (with needle down) when you need to readjust your hands or the quilt, and then slowly start up again once you're comfortable...like driving a car...ease up on the gas before you stop and gradually give it gas again when you start. I always thought that once you started free motion you needed to keep moving, and that's how I got myself into the most trouble...pointy curves, giant ("toe-catcher") stitches, etc. (love that class, by the way)
