With my current series of drawings, I am giving myself the permission to stop a drawing whenever I want and then start a new one that is a copy with additions. For example, these two drawings were both started with a different intention in mind.  As I began the bottom one with the felt tip markers I liked the way the white of the paper was interacting with the fading marker stripes, so, I stopped at that point and began another.  The top drawing became a conversation with the first and I wanted it to speak to the silent white space of the first with a voice that spoke in a similar volume as the faded stripes. Working in this manner has allowed me to look at details of similar ideas that are expressed in different mediums.
