Pencil Drawings
The common pencil, used by draughtsmen around the world, is the most immediate and sensitive of the drawing media, being as capable of producing a quick sketch or a finely worked drawing. Pencil marks vary according to the hardness of the graphite lead in the shaft. The harder the lead (and the sharper the tip) the finer the line. Pencils are a dry medium, in contrast to pens which apply liquids.
