While waiting for the paint to dry on the wreath, start working on the creepy eyeballs. Use a permanent marker to draw a circle with a little notch taken out of it (almost like a Pac-Man shape) in the middle of a Ping-Pong ball. This will create a catch-light in the eye which makes it look more realistic. Color in the shape.
Choose an eye color (blue, green or brown) to make the iris. Follow the circle that you already created for the pupil with the colored marker. To complete the catch-light, create another notch in the iris, lined up with the notch you already made in the pupil. This should give you a full circle of white in between the pupil and iris.
To make the eyeballs look a little creepy, use a red marker to draw veins on the side of the eyeball. Start at the bottom of the eye going upward toward the pupil and iris. Repeat the whole process until you have enough eyeballs.
