I agree that the price is too low. If you were doing it just for a gift or partially a gift, it would be different, but she wants you to make her one. If she pays for all of the materials, do you think $100 would be worth all of the hours to do it in? I think you should do it for the price YOU feel comfortable at, if you think it sounds too high, and she does too, she doesn't have to have you do it. It takes a lot of time and patience and work for a quilt...any quilt, but the price is something you should feel comfortable with. You could always check prices online like the others mentioned.
