I recently made these cookies for a sweet girl who just turned 6. She wanted aquamarine cookies. No Theme. The first thing that came to my mind was mermaids. Luckily, she loves mermaids too! I first iced the cookies in white, after they were completely dry, then airbrushed them with a mix of Americolor sheen sky blue and leaf green. The polka dot stencil is from The Cookie Countess.
Then drew the mermaids using my Kopykake projector and edible pens. First filled the tails, then the hair and eyes. Finally the skin color. After that was dried I put some edible pink dust on her cheeks and drew the mouth with a red edible pen.
