I draw all the time, on all kinds of surfaces. My subject, to use a rather narrow term, is always what I am thinking about at the time or what is going on around me. I make marks sometimes, just to feel the pen on the paper. These marks turn into something, sometimes a recognizable something. A phrase gets stuck in my head, this gets written in somewhere. I see a person sitting, or a pipe coming out of the ground, or a tree branch, these things go into the drawing. I make a lot of my art like this, starting out with no set direction, but ending up going somewhere I intended to be all along. There is no randomness, there is no automatic drawing, there is no spiritual communion with Deity X, there is only a mark maker and intention strung between choices and me.
