I love Vampires, but my fave is Eric Northman from the Charlaine Harris book series. Which is the basis for the hit HBO show True Blood. I'll probably make alot of stuff deicated to that however if there is a quote or saying some wants on a shirt but has yet to see let me know and i'll be happy to make it for you.
My newest influence is the two series from Cassandra Clare, The Mortal Instruments Series, and The Infernal Devices Series. they feature Shaddow Hunters (demon slayers), Vampiers, Werewolves, Angels, and warlocks. I suggest these book to anyone who likes anything remotly connected to this stuff! not to mention the great sayings Clare gives her charaters that inturn I can use on T-shirts, Mugs and other great stuff for you guys!
