I like Sewcrafty's idea of the shopping trip. Then you could use what she is interested in to work her into an easy BOM by suggesting it while shopping. If she doesn't take the bait and swallow the hook, then I would drop it.
The next tack would be to give her small things she will fall in love with that you make. She make pick it up from there.
Another tack down the line a bit would be to say you wished you had someone who was interested in quilting to leave all your toys to.
