I am running out of space for my books. If I had my way there would be stacks on the floor as well. The other side of the room is no better. It probably wouldn't be such a problem had I not wanted all my stuff in one tiny room. As you can see from the overexposed picture I also have my collection of toys, arts and craft stuff here. This is simply because I need a place I can close the door on to the outside world. Plus, since I do all the cleaning, I like the rest of the house to be sparse enough for easy vacuuming, dusting, wiping, sweeping, mopping. Mess control if you will, although with a toddler on the loose that's a bit of wishful thinking :)
