I'm not against them... but then again I have two of them, so I guess I wouldn't be. And plan on getting one more.
But being that I am such a conservative, only really visible one is on my ankle. Its a yin and yang with smoke all around it. My second one is on my shoulder blade and its the triple moons, (waxing,full moon, and waning moon). My final one will also be another hidden one, and that will be on my tail bone, It'll be a very very detailed one. A Sorceress, a cauldron in front of her, a willow tree to one side, a raven, a small puddle of water with her toe sticking in it, and naturally fire for the cauldron, basically all of earths elements will be represented.
Even though I'm for them, I'm really not into 'heavy' tatooing. I like them visible when I feel like and still be able to put an elegant gown on to go a business thing with my husband.

The hidden bad girl thing? LMAO
