I took a FMQ class and one of the best things I did was buy a practice cloth with all of the different FMQ stitches outlined in black on the muslin. My instructor sold me a piece of tempered glass and I covered the edges with painter's tape. I use a felt tip pen and put the glass on top of the pattern I want to practice. I can do the same design hundreds of times until I am comfortable with it. I just wipe off the glass and try again. It works for me.
