First find an image in a magazine you want to use. Grab some clear packing tape, scissors and a spray bottle with water and some sandpaper.
Put the tape onto the front of the image you selected and trim away excess tape.
Rub the tape down onto the image. Check to make sure there are no air pockets.
Mist the back with water and begin to rub the paper off.
Adhere the transfer, tape side up, onto your painting using soft gel. Let it dry for a day or two.
When the gel is completely dry and adhered to the surface you can then pull the tape off and your transfer will stay.
