My answer to that problem was a mannequin arm. I drew my design on it and took it to the tattoo shop. After I assured my tattoo artist that he had artistic license it became our project. It was good to have my own art work rendered by another artist. It made the experience even more personal.
Heres a couple of pictures. I kept the "arm" because I'm not finished yet. I have some more space to fill up, lol.
