Card Catalog Quilt.

I love that SO much. If I had thought to save a bunch of the card-catalog cards when my library scrapped theirs, I'd totally make one. Even if it meant having to buy a scanner.

(I suppose I could do a mock-up one, typing the "card material" into a program like Corel Print House and making iron on transfers for the cards. Or even hand writing them with a pigma pen. How wonderful would it be, to have a quilt with the card-catalog cards of all the books you love most!)
