I make two kinds of ACEOS. One is a glossy photo of a pile of my beads with some scrapbooking-type embellishments added. The other (above) is actually made from polymer clay cane work. I make the art right onto a playing card, bake it, and then peel off the card and sign the back of the clay. This one, Desert Tiles, is my favorite so far. See my whole page of ACEOs here.
There are lots and lots (at this moment 6578) of ACEOs for sale at etsy, and I searched the site for ACEOs made by my friends at the polymer clay artists guild of etsy (PCAGOE). Turns out that so far, just a few of us are making them, and even with just these few, I'm amazed at the diversity of talent in this group! (Click the highlighted names to visit their etsy shops!)

Lost Souls by ElizabethBonura - This one amazes me. It's an entire 3-D sculpture, and shiny to boot!
So there you have it, folks, the world of ACEOs!
