Before you start cutting it's important to plan where you want your bottle and battery pack or controller (if you're using lights that have them) should be located. Your bottle will require a hole in the top cover. I suggest choosing an off center location, leaving room to use the open part of the book to display some nice tchotchke. The hole for the batteries or controller will go in the other side, but should be near or adjacent to your hole. Sketch out your cuts in pencil. Also, keep in mind that your book needs to be thick enough to sufficiently anchor your bottle and fit your battery pack or controller.
