I've made this ACEO from Polymer clay in blue and white and added a silver metal fish and starfish, pearls and glass gems. It was 'antiqued' with acrylic paint and then touched with pearl blue and silver metallic paint. A shimmery underwater scene! The glass gems remind me a liquid droplets and the tiny silver bits of clay sparkle like bubbles. It measures 2.5" x 3.5" which is the required size for an ACEO. ACEO stands for 'Artist Cards Editions and Originals' and can be made of any medium, the only rule is their size. They are tiny affordable collectible works of art! For sale in my Etsy shop.
