Whats wrong with a piece of paper and a pencil?
It doesn't matter if you can't really draw, as long as you can get your idea across, any half decent tattoo artist will re-draw your tattoo properly anyway.

Please don't get a tattoo, you might like it right now but in a few years you will probably regret it. As you get older it will stretch and sag and you probably won't be able to tell what it was of. Also a lot of people think tattoos are trashy.
