I saw these posters in Martha Stewart's Halloween magazine. She's selling them for 15 dollars for the 6 poster set on her website.
But I think we all know its MUCH more fun to make things yourself.
These pictures were taken from my Blackberry and do not do them justice at all.
I printed the pictures on my printer, ripped off the edges for a worn look, dyed the paper with tea and then singed the edges with a match. Some of them were still a little wet when I took these pictures.
The zombie one is my favorite. =)
