Clueless

I want to get a tattoo to represent my twin little girls, but I'm clueless as what to get. Everything I suggest, my wife doesn't think will look good. Of course, I'm just throwing suggestions and hoping that she'll inspire me with something. I'm getting nothing though. If anyone reading this has an idea of what a good tattoo for a father to get to represent his twin daughters, please leave a comment and let me know. I'm stumped.
