Do you have any quilts already made that you could offer her? I know that I have a few just collecting dust that I never Use and no longer cherish. I would get input on colors then make a simple DP9. IF you are so moved. People really dont need to be involved in "choices" besides the colors. Otherwise it will get complicated. If she as admired a specific quilt that you have made, perhaps that would be a starting point. Keep requests simple. Or decline. Your choice always.
