I did a second project making a flexible embellishment out of gel and paint. I mixed 50% white Liquitex thick paint and 50% Liquitex Gel, mixed well. Ink the stamp with black Stazon and spread a tick coat over the Betta stamp. Let dry overnight. Peel off from the stamp and trim if needed with scissors. I tried coloring with Copics, Pebeo acrylics & Inka Gold (Rose). They all worked so I used all on the finished fish.
I stuck the fish on the acetate just to see how it looked:-) I applied it to an embellishment jar to show how flexible it is.
