Learning to drive a sewing machine
If the girls are new to the machine some machine practice on following lines using paper and an old used needle would help. Use a marker to mark straight lines, then gentle curves, squiggles with and with out points and something with circles. I start with a fat marker for the first attempt and then go to a thinner one and then a still thinner one. Going from fat to thin gives them success all along the way. Just remember that if they are new to sewing machines and quilting there is more room for error. Master the machine anda then put it to the fabric. When you don't succeed you're mor likely to give up or say you don't like it without it ever having had an honest try.
