You are absolutely not alone! FMQ takes practice (as said by others) but more than even practice, I believe it takes "relaxing". I'm still "practicing" and I am improving although no way near what I would like. I do find, however, that I am fine until I start over thinking my FMQing. If I just quilt and not over think it, I seem to do better. Meyert is right! No one else will even notice that the stitches aren't all the same or that you quilted "outside the line". Be sure to not point out what you believe to be your mistakes.
