Ten Simple Steps to Hanging Wallpaper

Step Six: Booking the Paper

With the paper still moist, pick up one edge of the paper and fold it over to the center, without creasing the paper. Do the same thing with the other edge. You should not be able to see the back of paper. Don’t worry; it will be easy to separate later. Fold the paper in half again, and another time if necessary taking care not to create any sharp creases—this process is called “booking.” Let your “books” sit for about 5 to 7 minutes. This allows the adhesives to take effect, and for the paper’s width to expand to its original size.
