This has become a signature project for the middle school classes and it's one of my favorites! We begin by taking a photograph and drawing a half inch grid over it. We then draw a 1 and 1/2 inch grid over a large paper and transfer the information to create an equal ratio. The students love this project because the drawings are so accurate and proportional! We then use oil pastels to create realistic values that make the drawing more dimensional. The results are fantastic and really capture the look of the artists!
