I've been working on a couple pallet projects so I had a big pile of pallet wood scrap in the garage. I found a vintage glass door knob at a little estate shop a few days ago and thought it would be perfect to hang coats. Easiest project ever. I grabbed a piece of wood out of the pile and sanded it a little. Didn't even cut it to make it even. The three glass hooks are new from Home Depot and I just used a bolt to attach the door knobs.
UPDATE! I found this great tutorial on Beckie's site Infarrantly Creative on how to fill the doorknobs with resin to make the knobs easier to screw in.
Also the "glass" hooks are actually acrylic and are called the Liberty Acyrlic Facets Hook and I bought them at Home Depot.
