If you want to get into the holiday spirit without having to cut down a poor, defenseless evergreen, check out this clever idea from the resourceful folks at the Gleeson Library in San Francisco. They stacked a bunch of their own books (bound in a rather apropos shade of green) to form a perfectly proportioned recycled Christmas tree to add cheer to the space. The best part? Once the holidays are over, all of the books go right back on the shelves they came from!
