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. ,:I!~ 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. 130 /ARCHITECTURAL GRAPHI CS
