Exercise 6 Blind contour drawing

Blind drawings are the third technique used by artists as a warm-up exercise. It also forces us to observe creatively instead of logically.
You can create blind drawings of any object including your non-dominant hand, an eggbeater, a bottle opener, a shoe, or a chair.
If you cannot turn away from your drawing or you find it impossible to take a peek at your drawing, make yourself a screen by making a hole just big enough for a pencil in a square piece of cardboard.
This demonstration video shows you how to create the cardboard screen, do a blind contour drawing and a pure contour drawing of the same subject.
