After some thought, we each decided to use the chair backs to build a bench. Les created hers first and used it on her deck (I don't have a picture of hers). When I was ready to build mine, I didn't have the tools I would need to make the cuts so I drove to her house with my chair backs so we could build the bench together.
Before heading over, I did some searching around on Pinterest for design ideas for my bench. I found several that I liked and bought the wood I needed to create the look. I bought one 1" x 8" x 8' board, two 1" x 4" x 8' boards & two 1" x 3" x 8' boards.
