I feel like it is almost time for me to get a tat, lol.
I want a Harry Potter one, but I'm not sure what exactly...A Snitch? The Deathly Hallows? Always? A great Dumbledore quote? There are so many options! I've also toyed with the idea of a Dumbledore patronus...because like @stpete, I love the idea of a phoenix burning in flames then rising out of the ashes. But I'd want it in a blue color-scheme since patronus' (patroni?) are blue-ish. I also like the Expecto Patronum means "I await a guardian". But until I figure out exactly what I want, I wait.
Love this one, it's simple and kind of sexy, but ouchy!
How often do regular, outline-style tattoos have to be touched up?
Mine are all black and gray, but I put sunscreen on them every day and have never needed a touch up. If you make sure to take care of it, you may never need one.
