My daughter and I spent about an hour picking out backing fabrics for most of the quilt tops I have around here. She has a great eye for color and isn't afraid to say, Mom, that is ugly! What am I going to do next year when she goes off to college. There will be a lot more ugly quilts in this world :) I will have to make her help me when she comes home for breaks.
I haven't counted yet, but there are enough paired tops and backings to get me through to Christmas I think.
