I recently turned a room in my home into a dedicated office/studio space, and was in need of closed storage. Without a budget to purchase anything new for this room, I used an IKEA locker cabinet I already had and made it fit to the modern rustic style of the room.
I simply cut two reclaimed barn boards to fit the top, sanded them smooth, and then used gorilla glue to secure them. This gave me another surface butted up to my desk where I can spread out and work.
I jimmied off the lock/key sets on the doors, which left two big gaping holes. I had two large wooden knobs to use as knobs and so to make them stick I used magnets on a flat piece of hardware on the back of the door, then glued a nickel onto the knob, making it stick to the magnet and be usable to open the doors.
These simple hacks really change the look of the locker and make it both beautiful and functional in my home office. You can check out the whole room here. Simple is always better, isn't it?
