Sketchbook Studies is literally a series of contour-line sketches from my sketchbook, begun shortly after arriving in China. They were primarily intended as an exercise for keeping my hand in drawing, while adapting and acclimating to a new culture and surroundings.
Done very quickly, in a gestural approach of just a few minutes, they are often "riffing" off the Circadian Loops series in terms of their circular, overlapping, positive-negative spaces.
