I'm guessing from your name that you have accomplished a few years of sewing, either quilting or apparel. I think my biggest problem with FMQ was coming from years of sewing. I wanted to do everything forward. Give yourself permission to sew sideways and backwards. Once I did that my FMQ was possible. Practice your desired out come, curls or whatever, on any surface with the index finger of your dominant hand - there's a correlation bewteen that finger and the brain. A slightly textured surface might be better. Don't go to the machine until the motion feels smooth on your practice board.
