Complete A Face:

Find a picture of a person's face. It can be from the internet, a newspaper, or a magazine.
Make sure to find a large, front view pose. (Also, a black and white picture is better than one in color since you will be using a graphite pencil for this assignment.)
Cut the face in half, either down the middle of the nose to divide the left and right sides or in some other way.
Remove one side and glue down the other onto your drawing page.
Do not throw away the removed piece since this will be what you will have to copy!
Draw the rest of the face to connect with the glued/taped down section. In other words, "complete the face."
Keep the removed section and tape it to the left side of your book (page 4).
