Did I secretly sketch the polar bear before drawing? A lot of you did actually see the outline and if you look very closely, some of you can probably still see it. Except it isn't there. This is regular copy machine paper, there's no pencils, nothing. You don't need a sketch to draw a polar bear in a snowstorm. It's a very, very old joke. With a fact that so many of you saw the outline, says something very interesting about the human mind. We're built to see lines that don't exist. This is what drawing with negative space and drawing itself is all about. The outlines that makes the drawing work only work because they replace the imaginary outlines your brain dreams are. And now I'm going to show you something freaky that you'll probably hate me for. Using negative space you can draw the perfect shape just by letting your viewers brain fill in the blanks. And the best way to mess it up? Just make the outline. Bye.
