i find the best way to practice is to do loops, meandering, straight and curved lines and points. You need a lot of practice to do free motion successfully. Go as slow as you need to in order to make even stitches. Work until you find a good balance between the speed of the motor and the movement of your hands and.....never, NEVER take your hands off the fabric. if you need to stop then stop with needle down and reposition your hands for better grip or to turn the work for better visual. Then do a small practice piece each time before you do work on your quilt. You need to get into the rhythm of the quilting.
