We had lunch from Le Pain Quotidien at work a few months ago and I took the plywood tray that held the desserts back home with me. The wood was a really cheap material but I figured I could turn it into some sort of better looking tray for almost no cost. I primed the tray to help reinforce the wood, and then painted it a light sea foam green that I mixed from my own paint collection. I finished the edges with some gold paint so it looked a bit more polished and then sealed the tray again. It was so easy and I can't wait to use it for appetizers. Plus, it didn't cost any money!
