A while back I posted about bringing home a few apple crates from my dad's farm to use in Brigham's bedroom. At the time, I wasn't entirely sure how I was going to use them, but after bringing them home and realizing they have spent many years in a barn and are brittle at best, I thought mounting them on the wall would protect them best from busy toddler hands. Plus, they serve as a place to show off his 'stuff', or whatever that means when you're two! I love how these crates look in the room. They're such a perfect fit for a little boy.
If you want to give this a shot yourself, the only tip I have is that I wouldn't mount the crates directly onto the wall. I had a few pieces of wood (1" x 4" I believe) cut to fit the width of the crates which I nailed on to the back to offer a bit of extra support. I then drilled directly through the back of the crate and through the supporting wood into the wall. You can see the screw heads in the image above and in the very top picture you can see the edge of the wood peeking out.
