Sometimes (most times) when my mind goes completely blank looking at a fresh page of my sketchbook, wondering what to draw, fearing an uninspired, ugly sketch, I turn to the comfort of crayons. The sensation of just rubbing a rich, creamy oil pastel crayon on a sheet of paper feels almost cathartic. And the resulting page with its saturated, textured colours is quite satisfactory to look at.
I always keep a box of crayons handy, for inspiration is a moody thing, you never know when it decides to fly away.
