Measure the finished size of your artwork using a measuring tape.
Measure and cut a piece of self-adhesive laminating film 1 inch wider and longer than your artwork. Roll out the film on a large surface, mark the measurements on the film with a pencil and cut the film using either a rotary cutter or scissors. To use a rotary cutter you must place a self-healing mat underneath it to protect your furniture.
Peel off about 1 inch of the backing paper on the film; attach the exposed 1-inch sticky area of the film to the side edge of a table. You will be rolling the sheet of film over your artwork on this table, so you'll want to work a smooth surface such as glass, plastic or varnished wood. The film will not permanently stick to smooth or shiny surfaces.
Place your artwork flush with the edge of the table, centering the artwork in the middle of the film. Make sure the film will overlap at least 1/2-inch on either side of the artwork to leave a border that you can trim.
Pull the backing from the laminating film a couple of inches at a time and press the film onto the artwork. Lamination film is pressure-sensitive, so use a soft cloth to rub the film over the artwork to make it stick, remove air bubbles and create a smooth, finished appearance. Continue to pull the backing from the film and rubbing the film onto the artwork until you have covered the entire piece with film.
Peel the artwork from the surface carefully.
Trim the excess film from the edges of the artwork using your rotary tool or scissors. Work slowly to cut a straight edge along the edges of your artwork.
