Take a picture of your eyes with a digital camera. Make sure that they are "angry" eyes. Take several shots to give you a variety to choose from and don't worry about getting it perfect. You don't even have to use eyes from the same shot. My example above uses eyes from two different photos pieced together in Photoshop.
If you don't have a digital camera, borrow one. I suppose you could always smash your face down on a scanner but chances are that you would go blind and never even get to see the end result of this awesome project. So keep your eyes outta' the scanners kids!
Print the eyes out and move them into position for the cutout eyes of the portrait. I had to adjust the positioning of my eyes in order to fit with the portrait. The image above show how much "extra space" I had to add betwwen my eyes to make them fit correctly.
Cut out the photo of your eyes and glue it to a piece of foamcore. Make sure that the foamcore is larger than the photo. Try to give a 1" border of foamcore completely around the photo. In otherwords, measure your photo and cut the foamcore two inches larger in both hieght and width, the center the photo.
Cut a second piece of foamcore the exact same size as the previous piece. Now cut a hole in the second piece that is the same size as the photo of your eyeballs. What you are essentially doing with this second piece is building a frame to glue overtop of the original piece. This second piece of foamcore give you a quarter inch of depth for the photo of your eyes,
