The base is a wooden oval from Lowes that I spray painted white. The figures, grass, and flowers are made from polymer clay.
I began with aluminum foil over wire armatures, then covered it with Super Sculpy for the first baking. (I left wire extending from the feet so that I could attach them later to the base with a staple gun.)
I added colored sculpy for the suit, dress, hat, hair, etc., then baked again. (A pasta press will make the clay flat to use to cover the plain sculpy). I attached them to the base, and baked again. Then I added the grass, flowers, and his arm around her shoulder and baked again. Lastly, I glued on the pearls.
