My doodles tend to start in the center and spiral outward. The flower-like shape in the lower right began with the circle in the center. The shapes with rectangular centers were begun by making quick zig-zags between two fingers.
This one reminds me a little of a Japanese noren - the half curtain that hangs over some doorways. In part, that may be because the color of the ink is close to the traditional blues you see in some Japanese textiles.
Once forms start to emerge in my doodling. I'm then feel the compulsion to color between the lines. Although shading would be a better term for it. These doodles were the result of another client call. You can see my notes: "People interacting with technology." Fascinating.
