Thanks for the comments guys and sorry for the delay in getting back with some of you, I've been in CO chasing mulies. It was old board fencing surrounding and old barn. The middle strips are actually siding from the old barn. I originally wanted to only use the barn siding, but termites had destroyed the majority of the boards. The dimensions are roughly 30x24. I used 6 inch screws as hooks. I painted the screws to make them look weathered.
I'm about the least creative person on earth, so I was proud of how it turned out.
