Don't forget the glass of wine. You need to be relaxed to do FMQ!!! :roll:
Seriously, like others have said - start small - I always recommend pot holders so you don't feel like you have wasted the effort. Then move up to a small wall hanging or baby quilt. After you have the technique down, then try a larger item where you are dealing with fitting everything through the machine.
Good luck and don't get discouraged. I still have good days and bad days with FMQ, but the good days are winning.
