Once your canvas board is dry, use a damp sponge to wet each of the images. When the paper appears to be translucent, gently rub it away with a scouring pad or rough plastic sponge. As you remove the paper, the image should remain on your canvas board. Let the surface of the board dry. If there are any whitish areas remaining, wet the images again and try to remove as much paper as possible.
Tip: Remove all the air bubbles to achieve a clear image transfer.
