I have no judgements about tattoos really. I have just never found any piece of art or any words that I would want to see on my body permanently. If I did, I might consider one. There are some beautiful tattoos out there by skilled artists.
Me neither. Most of the time when I see them, I just think, Bleah, that doesn't look that good. The ones I hate the most (not that it's any of my business, of course) are when people just get a tattoo, and then another one, and then another one, all kind of random, having nothing to do with one another, and just kind of randomly placed here and there.
Interestingly, the ones I have seen that I thought were gorgeous have almost all been people who decided to do one coherent design/theme over an entire area of their bodies. I saw this guy on vacation last January who had these very geometric lines and shapes/patterns tattooed all over his entire upper body. All black, no other colors. He looked freaking great -- the effect was just stunning. And I read a book recently where one of the characters had a dragon that covered most of his body -- the flames licking up the sides of his head, the body tattooed across his back, the limbs snaking around his torso, and the tail wrapped around one leg. That sounds amazing.
