So I have been moving around a lot and had accumulated a large amount of milk crates, but after unpacking had no where to put them and had my mattress on the floor. So I combined the two making a really great place for storage and no clutter (i.e. milk crates lining my wall).
What you will need:
About 20 milk crates or other similar sized storage (I used a mixture of crates, boxes and plastic tubs)
