Repurposing Crates as Shelves

I recently got about five of these crates  I knew I would use some to display my things at the farmers market, but I wanted to put the rest to use as well. My bathroom had the perfect spot on the wall to be filled. 

I attached some picture hooks I bought at Home Depot to the back, as well as measuring out the hooks on the wall it would hang on. 

I realized that the crate was not level and tried my best to compensate for this while placing the wall hooks. It didn't end up being perfect, but..close enough. 

I plan on staining the crates with a homemade steel wool-vinegar solution that is currently soaking.
