My granddaughters all sewed on my Bernina when they were about eight years old. All they need is GOOD instruction. The main thing to tell them is to keep their fingers away from the needle and not to watch the needle as it will keep going up and down but watch the area about an inch in front of the needle. Let her sew with you watching and see if she is paying enough attention to your instructions. If so, get her busy sewing strips for a quilt.
