This technique is known as crosshatching. Generally it is formed from a series
of intersecting lines. To go from light and dark, start with lines that are
spread out, with less intersecting lines and slowly overlap with more sets
of lines when getting dark. This technique is very common, generally because
it is clean and simple. See Video Demonstration.
This technique is for gesture drawings. It basically consists of scribbled
lines, which is rarely used in formal drawings. It's quick, and thus it is
highly recommended for quick sketches.
This is the circular technique. The pattern is made by moving your pencil
in a circular motion. The image to the left shows the quicker version of this
technique with larger loops. Variation in intensity is determined by pressure
and size of the loops. Loose circles is also recommended for quick sketches.

This is another form of the circular technique. The loops made are very tightly
woven, giving it an all-over smooth look. This technique is great for doing
the skin and clothing, but it does take more time. See Video Demonstration
This texture was achieved through blending. We've basically put on a layer
of pencil that varied in tone, and take our finger and rubbed it until it
was smooth. This technique is great for drawings smooth surfaces, especially
the skin, and is perfect for those who are less patient.
