Frog Island is painted with a combination of water-based opaque paint with opalescent pigments to enhance the deep blue hues and create shimmery effects of the background sky. Multiple layers of paint and glazes add texture and dimension. The sculptural elements of the island are made from real-life botanical elements – bark, reindeer moss, seeds, flower petals and semi-precious stones. The frogs are vintage brass figurines. The island is lacquered to preserve the colors of the botanical items.
