I made these with a bunch of friends a week or two ago. It was so fun, and really easy. It isn't vinyl at all, but printables! Yay! All the information (and printables) are found here at I Dig Pinterest.
I did find one of the swirl stamps at Hobby Lobby like she said, but the other one I got from Michaels. Then I also added in little bat and spider stamps here and there, you can't see them super well in the picture and I made 5 sets for myself, and I probably didn't choose the best example for those two particular stamps, but it did add something fun to the paper before we Mod Podged them on and nailed the corners.
