: Mark where the paper needs to fold over the back cover (leaving about 2 to 3 inches), trim any excess paper, and fold the edge inward. Slide the back cover of the book into this second pocket.

: Close the book and wrap the remaining paper around the spine and back cover to ensure it is taut but not so tight that the book won't close.

: Place the book back onto the folded paper. Open the front cover and fold approximately 2 to 3 inches of the paper's side edge over the front cover. Tuck the book's front cover into this newly created pocket.
