I like this - The base of the bird bath is simply three terra cotta pots (turned upside down, of course) in 14″, 12″, and 10″ sizes. The water container is a 16″ terra cotta saucer. The containers are held together with acrylic based silicone caulk. I also used the silicone to adhere the saucer to the top of the base. I further modified the project by adding a 6″ saucer to hold bird seed.
