It wasn't a bad or wrong way to paint; I created hundreds of works this way. There is no wrong way to paint. But from time to time I would find myself "stuck". When this feeling takes over an artist's process there is no more intimidating site than that of a stark-white blank canvas staring back at you as you second guess every creative intention.
One tedious self-doubting day a not-so-gentle voice (one of Mary's superpowers) ordered over my shoulder "Kill the canvas!" That moment changed the way I begin every painting. It doesn't even matter if the color you use to "kill" the canvas ever makes it through to the final product. It frees you from the sterility of the blank surface. The second-guessing fades away and mistakes are not only no longer worrisome, they are sometimes welcome.
So the next time you find yourself in a staring contest with a blank canvas just "Kill it!"...with paint.
