Where should I get my next tattoo?

I want to get another tattoo. I just want a simple cross, about a 1/2 in in heigth, just very simple. I’m trying to decide where though. I have a small one of three hearts intertwined on my right foot. It's up by my ankle and the start of my foot. Do you think it would be tacky to get another one on my other foot but up by my toes so it’s not completely symmetrical to the other one? Here are the other places I’m thinking…. Inner or outer ankle, shoulder blade or back of neck. Do you think that’s trashy? I’m also thinking (this might be a phase) the inside of my wrist….. but probably not because I want to be able to hide it…. I was thinking of getting one where the “tramp stamp” goes, but I just want a small simple little cross and I think you need a bigger one there…. (that’s next) lol….
