Lee and Carla covered your questions and concerns so well that there's really nothing to add! I would, however, stress what they both said about being patient with the process. FMQ takes a lot of practice to get your foot and hand/arm speed co-ordinated for those even stitches. But once you "get it", you've got it for good!! :)
And relax!!! Check youself every now and then to make sure your shoulders aren't bunching up around your ears! It's easy to get tense, which makes the whole process seem tiresome and frustrating. Really do concentrate on keeping your body relaxed. Good luck. I just know you'll get good at this in time.
