I think that if they want to sew, just get them started on something that works well and something that is not limited. When my niece comes over and wants to sew, she always cleans the machine first after asking the last time used. She's become a pro at cleaning at 8 years old. She gets the manual out to make sure everything is set up the way she wants. She is constantly supervised of course. She also gets on YouTube to check out the different tutorials.
