Well, in this lesson the high school drawing class discussed the use of lines, patterns, value (with sharpie which is tricky!) and emphasis. Each project had to have the following: variations on value (areas with more white, areas with more black, and areas with 50/50), at least 5 patterns, at least 5 different types of lines (wavy, zig-zag, straight, dotted, thick, thin, etc.), and an emphasis. Students used a cut out image from a magazine as their starting point.
Enjoy! I love all of these....but the cat one cracks me up every time.
