He attached 3 very old glass doorknobs, which came from my grandmother, to a piece of very old, weathered, wood that came from his Uncle Clyne's barn. I love the distressed condition of the wood - great character!
He drilled recessed hole in back so the knobs would hold firmly, yet sit flat against the wall.
I had a painting that I've been trying to find the right spot for. It's in a barnwood frame my sister-in-law gave me. It's goes perfectly with the towel rack.
Unfortunately, my lousy photo doesn't do either justice, but trust me - they look wonderful!
