During our line unit we used 4 different kinds of lines and some shading to draw the same cup 4 different ways. The first way we used contour line and demonstrated how varying the line between thick and thin can give a drawing form. We then used shading to draw the second cup to show it three dimensionally. Our fourth drawing we used cross hatching as a way to use lines for shading. Then finally we used a continuous line where you did not lift your pencil off of the paper to create a shaded and quick sketch. This is usually the most challenging since we are all used to being able to lift out pencils and realign any mistakes.
