Check this out. I think it's cool, and at the same time, I'm not sure I could do it without cringing. I'd want to use books that I don't want to read again, but I'd also want to use books that reflect my own tastes and preferences. And if I used books I liked, would I be able to turn them into bookshelves? I guess I'd have to use duplicates of books I like. What do you think? It is a great way to recycle!
