Sunflower This peice sells like crazy. The flower itself is made out of a cultivating disc with a screen in the middle for the seeds. The petals are made out of sheet metal. The leaves are shovels that are trimmed into the shape of leaves. The stalk is made from waterpipes that are different sizes. 1 and a quarter at the base and then narrowing to a half inch at the top. The base is a cultivating disc. Gabe makes them from 12 inches to 10 feet tall!
