: 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.
: Place your book in the center of the paper. Fold the top and bottom edges of the paper inward so that the height of the paper perfectly matches the height of the book.
: 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.
: If using a grocery bag, cut off the handles and the bottom. Slit the bag down one side or along a seam to create one large, flat rectangular sheet.
