Well, first of all, I wouldnt buy any "kids" machine. It would be much better to look in your local "sales" paper (bargain mart etc) and find a used model. I personally would find a singer, that has the set in bobbin (no bobbin case, thats too hard). And one that has an inner tension when you thread it (no tension wheel on the outside.) Other than that , simple is better, if you go to your local sewing machine store and tell them exactly what you are doing they can show you some, and might have some used ones as well. Good Luck!
