What to do with that box of old keys? Turn them into key holder organizer! It’s very easy. Simply use two set of pliers to bend the key into a hook shape, keeping the round part of the key (called the bow) flat. Make as many as desired. Next, stain or paint the board that you will use as the base. It can be as long as you need to accommodate the number of hooks you want to use. Use flat-head screws to attach the keys to the front of the board in an even line. Then, attach hangers to the back of the board and hang the organizer.
