First - I am an advicator of only getting tattoos if they mean something to you on a personal level. I really don't understand people that get cartoon characters or the same cardboard cutouts that the previous 50 people also got, but every person is responsible for their own happiness.
I have two tattoos that I got in the past year (one's 3inches on my right hip and the other covers pretty much my whole back), both of which I've designed myself, both of which were done by a reputable, licensed artist that came highly recomended by several friends. Neither one are furries (I do celtic knotwork stuff), but I have designed a dragonfly in the same style for a very dear friend of mine. I wouldn't mind getting something wolfish, but I'd have to design it myself.
My point is that because it's MINE (ie - showing off both my heritage and my skill) I'm proud to wear it - even if it will get old and wrinkly along with the rest of me.
... Great... now I'm trying to figure out a good design for a new tattoo... I should post the ones I already have (will make designs for others!)
Oh and major tip for those who've never had one but are considering: TATTOOS HURT! At least for me, they did. The outlines hurt more than the coloring, but after the endorphines kicked in I got all giggly so it wasn't quite so bad.
