Everyone has given good advise. If she isn't asking question and suggesting lessons, she just isn't interested. I have 3 daughters and one DDIL and none of them are interested in quilting. They all love the things that I make for them, but do not want to make anything themselves. I have 3 DGD who all want to learn how to sew. Just be patient and someday you will have GD's and you can teach them to sew. Grandmothers are wonderful in their eyes. That's been my experience, and if that doesn't happen, you will have many to gift with your quilts.
