On a whim, I picked up my silver pencil crayon. The silver gives some unusual qualities to the line as the tone changes with the light and angle of view. Somehow, it felt appropriate for what I was thinking about at the time, as I was full of thoughts about my mom-in-law and how her own abilities to think and perceive seem to change from moment to moment. Like her, this image looks different depending on how you look at it. (of course, none of this is apparent with a static scanned reproduction).
And with silver pencil again, got completely off topic and just had blast with colour (oil pastels on black paper). And again, on line it’s impossible to share the liveliness of using metallics for line work. If you have a silver pencil, just try it for yourself and you’ll see.
