I would take her asking you for a quilt as a HUGE compliment. If I painted and someone asked if I had any paintings they could have, I would be so proud!
You could offer to take a beginner's class WITH her. I did that with a friend and I learned a couple of new tricks and we had so much fun together! It didn't cost much and I used my stash. She thanked me over and over again for doing that for her. She said she felt too out of her element to take it by herself. I'm so glad I took it with her. Now she's a quilting machine.
Try to stay positive. It's sad to look at our gift in a negative light. Keep it as a positive gift and remember we are gifted!
