I'm a big fan of Pinterest, I even have a book board, I plan on doing a weekly update of fun book themed things I find there. As much as possible I'll try to link to the source, but sometimes, like above, the pin will lead me nowhere.
It might be something fun to do at our stall, although I'm not sure if people would pay for them.
This is a magnet by Bookfiend on Etsy, they have every kind of gift for the bookworm in your life. This sentiment is so true, there are so many bad films out there made from amazing books. Northern Lights, Possession, and Hearts in Atlantis are just a few that are popping into my head. What ones can you think of?
