Book Cover from Cereal Box

Step 2 Mark and measure the spine.

First, fold the Nutritional Information side of the box onto the inside of the front cover. You don't even need to crease it!

Now, mark the cardboard where the spine of the book touches. Stand the book up on its spine and mark on the back side of the spine.

Then cut the cardboard along these marks until you come just shy of the spine itself. There should be four cuts altogether in order to make two small flaps that we will bend back. Take the book out and tape these flaps down to the inside so they poke out a little from the spine.
