Thanks for all the ideas, everyone! I'm really liking the one pinksalamander linked, with some modifications. It says the drawing is copyrighted, if I e-mail the artist and ask if I can use it with some changes, do you think they'd let me? Would a tattoo artist here in town be willing to alter the drawing for me? I'd want it with the bunny looking up instead of down, and lop ears. Also, the foot not as curled because it makes me think of painfully overgrown toenails. I don't know much about tattoos, could something like that be inked in a color instead of black, and would it need a black outline?
I still like the bunny on the moon idea (I've seen a bunny on the moon since I was a little kid, there was a thread about it on the main forum a few days ago), or a flower like a tulip with her name in curly writing going up the side of the stem.
I had a customer today with several tattoos and I asked her where she got them done. She said she got them here in town at a place called Good Karma Tattoos and she said she really likes them.
I think I like the idea of putting it on the inside of my calf, right above my ankle bone. It wouldn't be too obvious and like someone else mentioned, I wouldn't need to worry about the skin getting wrinkly and stretched out!
