SCRIBBLING
Scribbling is a shading technique that involves drawing a
network of random, multidirectional lines. The freehand
natureof scribbling gives us great flexibility in describing
tonal values and textures. We can vary the shape. density,
and direction of the strokes to achieve a wide range of
tonal values, textures, and visual expression.

The strokes may be broken or continuous, relatively
straight or curvilinear. jagged or softly undulating.
By interweaving the strokes. we create amore cohesive
structure of tonal value.
• By maintaining adominant direction, we produce agrain
that unifies the various areas and shades of value.
• As with hatching, we have to pay attention to both the
scale and density of the strokes. and be aware of the
qualities of surface texture, pattern, and material they
convey.
