I didn't know the native Americans use them too?
Don't quote me, im not 100% sure. But I studied the American West and they look similar to those that were used by the Indians at that time, during rituals etc.
Though you're probably right, certainly more Viking etc...
I'm thinkinh of getting a tattoo, but as I was saying before, I think people do get them for the wrong reasons, and i know too many people who have done that in the past becasue they thought it would 'look pretty'.
Though I think with something like runes you get them for a meaning right? theyre a good conversation starter too, for people who are either interested in them, or who don't know what they are...
