Robin, You sound like you are creating a very special and unique garden or business for yourself. How exciting! If you type "sculpture and statues in gardening decor" in the search box you can find many sculptures made from many objects and bases. I have chosen one for you, but for such a broad topic, you need to see all the beautiful creations to narrow down your choices. https://www.hometalk.com/5207324/snails-i-would-welcome-into-my-garden
