I have succeeded in my goal of drawing without thinking, hence I have to remind myself where the shadows fell in the night still life so that I can tell the night still life from the daylight version. Having done that mental math, I can vouch for this being one of the drawings I made late last night. Had I the stamina to take the drawing as deep into shadow as I actually saw it, it would be a dense mass of lines for the late night lighting was spare. That would be a moody drawing. Got to do that some insomnious night.
But these drawings I made last night were little caprices to help me learn the forms of the still life as well as to ward off sleep. Sometimes you just want to stay awake a while longer. When the drawing is going well, I am reluctant to sleep. Just a few more lines ….
Go down that path far enough and perhaps the pen records your dreams …?

You may one night walk in your sleep and pick up that blue ball-point pen – give your subconscious some instructions before you sleep and let’s see what happens on the page – you never know – I tell my subconcious what time to wake and that always works 🙂
I’m working on it. Am sending my subconscious an email. Or maybe a tweet.
