Another thought would be to tell her that if she bought the supplies, you would come stay at her cabin & you could make it together. Stay a couple nights & if you don't get it finished by then, you could leave it there & set up another time to go back & finish it. Then you could let her know that she can work on it, herself, if she would like. She could then see what goes into making a quilt & just may take up quilting. I am always honored when someone wants one of my quilts. Sounds like, to me, she would treasure it just because you made it & it may be even more special to her if you two made it together.
