We have a cool basement (see post here). The Harry Potter Closet is a small closet in the 4th bedroom that is placed under the stairs. It is the kind of place kids love to play. Some of the older kids in our neighborhood--Hannah's favorite friend, Caitlin, and her brother Alec (they're from England!) came to play and decked out the closet like Harry Potter might have liked--including, unfortunately, writing all over the walls.
