@MrsPramm - Usually if a tattoo isn't going to work, and you go to a reputable artist, they will straight up tell you that it won't work and it's just a matter of believing them. But you'd be surprised where people have tattoos. I've seen photos of them on the inside of the lips, or even on the eyeball. And parts of the sole of the foot aren't as bad as others. I could see a small, plain tattoo being successfully done on the arch.
