Not exactly unique, but it is fun and pretty easy to make just about anything that you want. Initially I had a half dozen or so bows, and made several attractive holders by buying wooden plaques with routed edges from a craft store, drilled them for pegs, stained,poly top coat and done. When I moved and had more to hang, I went to Home Depot and easily found a nice piece of maple board with attractive grain in it and did the same thing: drilled, pegs, stained, poly and done.
Any board could be used and there are a variety of peg sizes and shapes to be had.
