This is a custom piece I did at the request of a couple remodeling their Central Texas home. It is approximately 6 feet across. the copper has been alternatively patinated and textured with either a torch patina, or a verde/green patina. Texture comes from a variety of hammering techniques. Included are three copper butterflies and three hummingbirds, all species indigenous to central Texas.
A piece similar to this can be custom made in a variety of sizes. This 6 ft size cost $5000.
