Example 4 columns 4 shading techniques

tips:

Keep your pencil sharp (unless you are stippling).

Rest your hand on a clean piece of paper to avoid 

unwanted smudging.

Use a soft clean cotton cloth (t-shirt) or a chamois

to smudge the blended column.

When stippling, don't be afraid to work fast.  Bounce the

tip of your pencil with a moderate amount of pressure

against the paper surface.  As your pencil bounces up,

move it ever so slightly to make a little dash rather than

just a little dot.

At the end, use a clean piece of paper to cover your work and

erase a nice clean edge.

More to come in class.

Remember, this is a practice exercise.  Pay close attention to

the amount of pressure required to make a desired mark with 

your pencil.
