We've been needing a key rack for ages now, so I thought I'd make one finally. Seriously, for the amount of time I've spent hunting down keys over the years, I could have made ten key racks!
This key rack is made from six pallet boards and a couple of 1x2 furring strips (at $1 each). It's gorgeous and very useful (and although we don't have 30 keys, it's nice to hang spare keys up, and I even hang my sunglasses here too). I'd just die if someone made this project as a jewelry holder.
