One of these is the packing tape/clear contact paper
transfer, a simple, easy and inexpensive transfer method. Find an image in a
magazine that you want to transfer and cover the right side of the image with a
piece of the packing tape, sticky side down on the image.
Next, soak for a short time in a bowl of water. Once it is wet begin in the centre and with your thumbs or fingers start rolling the magazine paper from the back of the tape until only the image is left. The really interesting thing about this type of transfer is that there is no white colour applied to a magazine page, so when you remove the paper, you are left with clear tape.
