I Love midnight book parties! I was afraid that after Harry Potter it would be a long while before another book was popular enough to have one. And with this series you almost have to buy the book to read it, at our library they had waiting lists with no less than 30 people on it for each book.
You've likely seen that at yours as well.
IMHO, a Twilight stencil would be popular. I know several people who would sub. just for that (cuz I don't give out copies
)and then make T-shirts, or whatever. Yeah, lots of interest in this series/movie. Who knows, if Ryan were to put out a stencil next year after the movie it would probably blow Napoleon Dynamite's record out of the water.
