I've been thinking about tattoos for a long time. I've never been able to come up with a design or idea that I thought was great and where to put it.
An idea came to me the other day that I do like. Iconic symbols from my favorite books, each roughly 1 square inch, down the side of my left upper arm. I've already come up with several of them:
The Symbol of the Deathly Hallows from Harry Potter
The Mockingjay from The Hunger Games
The One Ring from The Hobbit/The Lord of the Rings
The 7-pointed blue star from The Magician King
I really like this idea because it's expandable, explainable, not trashy, can be done in parts easily and, most importantly, because it's cool.
