If shrinking over a cast, you may want to cover any exposed skin with a towel to protect it from the heat. Using small circular motions with your blow dryer, slowly shrink the film to form it to your object. Begin in the middle and work toward each end. Be sure to rotate the heat back and forth to make sure it isn't concentrated too much to one area. The skin will have a wrinkled appearance, but will smooth out with continued heat. When heating near the taped seam, run your finger across the seam, to keep it sealed. Repeat directions for next piece.
FOR BEST RESULTS: Be sure to have a hairdryer that has high heat. If your skins aren't shrinking very quickly or easily, your dryer's heat setting isn't very high. Also, be sure to shrink carefully by the tape seam. Using less heat, while running your finger over the seam will ensure a perfect seal.
