Church in Venice, Italy; #2 pencil
Bear in mind that texture and pattern play a
very important role in the sketching of a building.
Patterns are used to suggest materials and
methods of construction. They are sometimes
used as tonal fillers to cover a void, perhaps a
blank wall. The purpose is to use them strategi-
cally to clarify the different layers of planes and
articulate the three-dimensional quality of the
object. Most of the patterns are made up of
different strokes that are drawn in many direc-
tions, from parallel lines to cross-hatching. The
key is to follow the direction of the plane while
avoiding obvious consistency and dullness. Always
use some diagonal pattern to break up the
monotony, and liven up the situation by reserving
some strong white planes for contrast. Use dark
shadow to exaggerate the depth of the space
and to enhance the readability of the subject.
