Last night students continued working with pen and ink. Nicole's drawing demonstrates the parallel hatching and cross-hatching techniques. We've already discussed the benefits of contrasting values to establish depth and define edges of shapes and forms. In addition to this, when using ink, you may also use various techniques and the direction of the "marks" to illustrate objects and their location. For example, the small jar in the foreground exhibits arcing, parallel lines moving across the contour. In contrast, the gas can behind it exhibits contrasting values as well as the cross-hatch technique.
