I've used these eyes this same way on several projects because they're just so creepy!
First I stamped and masked the house. Then I inked up the "spooky eyes" stamp and used it three times in succession, without re-inking. I masked the eyes, and sponged the background in two shades of purple.
It sends a chill up my spine! ack!
Stamps Used: Unknown (eyes--could be Diva Rubber), Karv'd (house)
