So, I am going to be a total slacker and instead of writing my own tutorial for this I am going to link it to Raising Olives rain gutter bookshelves. I haven't actually made mine yet but this is exactly what I am going to do. I will put pics up as soon as I put up my shelves. I am going to put 3 in my girls room, 2 in the boys room, and 3 in the upstairs hall. I am excited to see how they work out!
