I saw this idea on Martha Stewart's Website. I took a glass and the instructions called for melted chocolate to be piped onto the inside of a glass. I did discover one fun 'trick.' I had some left over chocolate icing in the fridge. I took it out and molded it, and then pressed it onto the side of the glass and I was able to manipulate the face. It stuck even when I added the frozen shake.
