I agree with the comments about taking her to shop for herself, then you could show her the many tutorials on the internet to learn the basics. She has sewing experience so there's no reason she can't do one up for herself! You should tell her you are simply too busy and she would much more appreciate the quilt if she puts the effort into making it herself - that's one thing you could really stress to her. Job done - be nice, but be strong. I can't stand when people try to wiggle their way into my precious quilt time.
