The line is the most basic formal element in art. Depending on how it is used, it can convey space, rest and repose, movement, stability or chaos. It can cause the eye to wander, or it can tightly constrain it. Lines can be made into detailed drawings, and yet the simplest squiggle can suggest the most complex of ideas.
I was recently presented with the challenge of producing work on the theme of "lines and curves". These pictures came about in quite different ways - one was stumbled across as I walked, and the other was carefully constructed. Both feature strong linear elements, yest they couldn't be further apart in mood and feel. That's the versatility of the line at work.
