Once the frame is dry, you are ready to apply the film. There are many different competing varieties of film available and each come with instructions. The basic procedure is to lay pieces of cut film onto the area to be covered and then ironing it to the frame. After adhesion, the film shrinks and strengthens the entire assembly. To achieve the greatest strength, it is best to cover your entire frame. Household irons work fine, but the small irons made especially for this purpose are excellent and not prohibitively expensive. Proceed methodically and you will be surprised at what you can produce.
