This is the third wine bottle holder I've made from an old skateboard deck. I find the decks in the alley near my apartment in Long Beach. Each one carries a unique patina from years of use. This one has colorful stickers and deep scuff marks.
On the back side, I mounted a piece of wood (1x4) which has metal keyhole hangers on the back. The hooks slip down onto two nail heads in the wall, making the whole unit very robust and secure. I use it to hold bottles of rum and vodka in addition to wine.
