Shiny red copper can dull into a natural green patina. We love this natural material and when we come by it it's often costly. But not here: these simple copper trays are currently on sale at Smith & Hawken for $16-$25. The trays can be used outdoors to hold planters or indoors for just about anything: a catch-all for keys and such, a serving tray, etc. A design this simple in such a beautiful material stands on its own throughout the years.
