Blind drawing with pencil

Blind drawing is when you look at what is in front of you and draw a series of lines that make up the picture. You don't look at the canvas and place your easel beside you with your body horizontal to the canvas and you are looking directly what is in front of your eye and not the canvas. At first I found the exercise stupid, but now I like it and it grew on me. I like the way you end up with a series of random lines and shapes. How very abstract! I was practising this technique with pencil at home, it relaxes your hand and makes you feel loose and not up tight.
