For those of us with lathe & plaster walls who can't/won't hang this sort of thing, why not bring all the crates together in an abstract shape, nail/glue/whatever the touching edges, and set the resulting shelving unit on the floor?
What a great way to recycle an old crate. I could use two of these in my living room. Since I do not have a coffee table, I could use these as side tables and then wheel them around to wherever I needed them. I am on a mission to find some crates!
