Try it without first. Just "doodle" to get yourself used to the motion. Just try to match your hand speed to the machine speed to get a good and somewhat uniform stitch length. Once you feel comfortable with the movement, do things like writing your name to get a feel for spatial placement.
Depending on the design done with FMQ, some designs are drawn first, and some not. Some people prefer to just wing it.
Try it without any drawings first.
And don't forget ... none of us ... NONE OF US ... were good at quilting without a lot of practice.
