The picts, angles, celts, scots of this isle wore woad. We were always tribally decorated. To me, having a tattoo is just the modern equivalent and it is something that all Britons should embrace. It connects us with our land, traditions and history.
I like girls to have them. However, they should have a meaning ideally, I don't like "it looked pretty". I have Saturn's sigil, Nemesis' sigil, the Star of David and the Monas Heiroglyphica. I will get more.
Aside from spiritual stuff, I would like one tattoo which says more aobut me than anything about spirituality. I would like a tattoo of Twilight Sparkle's cutie stamp.
