Foils are metalization on a clear plastic. To use, apply foil adhesive on a sealed surface. Wait until adhesive comes to a firm tack and place the foil onto surface. Rub the foil surface with a sponge or brush until the metal pattern comes off. The foil comes in rolls 12 in wide and is available in 1 ft. to 15 ft. increments.
TF- in front of foil means it is textile friendly
