no....not left or right. I am referring to how we strike or caress the painting surface with our tools. I believe that those of us with heavy hands need to learn how to caress the surface in appropriate passages. And, likewise, those of us with a more timid approach, must learn to bravely become heavy handed and bolder when the work requires it. I guess it seems similar to learning to play the piano....or any instrument for that matter. Fortissimo. Pianissimo. Over the years I have found that, in general, it is more beneficial for me to lighten up my touch. ( I am a natural heavy-hander). A lighter touch provides more glide. An energy that allows for more curve, more swerve. When I recently experimented with gold leafing, I was so very surprised at the light touch required, with a soft brush using circular movement, to actually adhere the leaf to the adhesive. (In my mind, there was a burnishing, a pounding effect....wrong) A light touch allows for more free play and more movement. To and fro. Ebb and flow. Push and pull. All good.
