I would definitely furnish all the supplies to do your quilt (thread, batting). I like the suggestions of help around the house but also might ask if I could stay and watch her do it and learn how to use her machine. In the end you might be able to barter some machine time from her and do your own quilts and develop a real quilting buddy. Perhaps she doesn't like to piece so you might piece a quilt for her and she quilt one for you.
