From simple angles, to squares, triangles, simple and complex curves to circles has been a plethora of lines, lines and more lines. LINE is a powerful element, and its applications are endless.

This final construction ended with interconnections among 3 circles--each circle providing a unit area for line joining and pattern development. You might consider other geometric and perhaps even free form shapes for other approaches to this type of line drawing.

The completed construction below is just one example of pattern and shape formations from the basic practice. You can originate many, many more.
