I always thought I wouldn't be able to get a tattoo a they were painful. But the desire for one was great. I took years to decide what I wanted and it always came back to two things, Tolkien and Alice in Wonderland. The tattoo for the latter was too complicated and I had no idea if I could stand the pain or the sittings it would take. I had seen a couple of friends with their amazing colourful gigantic tattoo and heard the stories. So I went for an illustration from one of my favourite books from childhood and adulthood too. Smaug.
My sister and I got our tattoos on the same day. Her's was one she designed and was her second. This was my first tattoo. As I could stand the pain, I got another a year or so later. My little tribal fox was planned almost as soon as I got my first but I took my time to get it. I'm working my way up to something more intricate and also saving up for something more detailed, but it all comes down to whether I can stand the pain. In a world where tattoos don't hurt, these would be my 'geeky' choices.
Of course I would have an Alice in Wonderland illustration, ideally involving the Cheshire Cat.
I love Tolkien's world and I think a tattoo of the Leaves of Lorien would be beautiful.
