...Make photocopies of the images you’d like to transfer. This step is very important — simply printing a photo from your computer unfortunately won’t work. Next, decide where you want to transfer your image. Paper seemed to be the easiest for us, but this can also be done on wood, ceramic, and tin.
Flip your image face down, and hold in place while you completely cover the back using a blender pen. Keep in mind that your transferred image will appear as the reverse of the original — like a mirror image.
