Stackable bins with wheels travel from bedroom to playroom and even out to the garage. Open bins are a good alternative to bookshelves for holding all sizes and shapes of children's books. Stackable storage is a great way to corral smaller toys―jungle animals, play tools, and action figures. You can use plastic photo, file, and clothing boxes. Just don't pile bins too high or form precarious constructions that will bring out the climber in your child.
