a few small pen sketches from 2014 or so. i remember approaching these as a challenge to myself to prioritize abstracted areas of value, and to communicate them using only line patterns/weights. there was to be no actual cross-hatching or shading, with value relying solely on line density/direction, and minimal outlining (and being ink, no going back to correct any mistakes). often times i found myself getting better results in sketching practice when i would impose these little made-up sets of rules/criteria for myself, as opposed to leaving myself free to fuss about without parameters. while not two-tone per se, these struck me as vaguely similar in spirit to the notan exercises we do at the waichulis school (which i am sorely undisciplined with – something about sketching with charcoal just makes you want to shade!)
