Blue marble and flowers, decorated flat egg, refrigerator magnet. This refrigerator easter egg magnet was made not made with half a chicken egg as the mold, rather, a rounded solid piece of white polymer clay, and a thin sheet of marble blended clay over top, and trimmed with a knive around the base. The arc of the center of the egg shape is much lower, and this is an easy alternative to making the egg shaped magnet with half a chicken egg as the mold.
The flowers leaves and stem were added after the whole egg base was complete, but I believe the marble sheet and flowers can be added at the same time.
