Cut out a magazine image and adhere to a card base. Lightly paint gesso over the image using a dry brush and a crosshatch motion. This softens the image, while allowing you to still see the image.
I added more gesso to the images I did not want to show through on my card.
After the gesso dries, use a fine-point pen or marker to define the area you want to bring out. Add extra details to the image and background that you desire.
