Plug in a hair dryer near the location of the wall transfer. Turn the hair dryer on medium heat, and hold it 6 inches away from the transfer. Move the hot air constantly over the entire transfer for 30 to 60 seconds to soften it.
Peel up one edge of the wall transfer, using your fingers or the tip of a knife. Once the corner is raised 1/4 to 1/2 inch, grasp it with your fingers.
Fold the corner of the transfer upward, and pull it away from the wall, using a slow, smooth, upward motion. Continue until the entire transfer pulls entirely free from the wall.
Apply 1 tsp. rubbing alcohol to a cotton ball, and rub it over the area of the wall where the transfer was previously applied. This removes any remaining sticky residue from the wall.
