As a former Home Economics teacher I recommend a simple, lower end, name brand machine that has a good track record. Too many bells and whistles will only confuse her and a machine with inherent problems will discourage her. I also recommend classes or 4-H if available. Otherwise, I think you should schedule 'sewing together' times and teach her yourself. It would be good times besides. Projects should start out being simple and done quickly. But, don't discourage her by giving her a machine that is not reliable and no guidance.
