Remove the cover from the book. Unfold and flatten the book cover so that it lies smoothly.
Plug in the laminating machine, allowing time for the machine to warm up. Most machines will have a button indicating when the temperature is prime for lamination.
Place the book cover in the laminating pouch. Make certain that the book cover is centered in the laminating pouch. Smooth the laminating pouch so that there are no gaps or bubbles.
Select the highest speed possible on the laminating machine. Depress the start button. The motor will begin to grip the laminating pouch.
Feed the laminating pouch into the laminating machine. Pull gently on the pouch as it comes out the other end to decrease air pockets.
Cut excess lamination from the ends. Leave at least 1/4 inch of lamination. If you cut too closely, you could sever the lamination seal.
