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)
Step 1: Arrange the crates
Not all of my crates/boxes were the same size so I tried to put the larger ones at the head of the bed and used flattened boxes to raise the level of the others while also adding a little cushion.
