complex curves

"... assumptions you tend to make of familiar objects can distract you from looking carefully. Distractions can be reduced and sketches made more interesting... " by selecting man-made objects with complex curves.

I didn't find this exercise as inspiring as some of the others, and decided to take note from earlier in the book where Laseau states "As beneficial as drawing is to the designer, real skill develops from the pleasure that you get from drawing... draw only what interests you... "

Proportion and accuracy of profiles becomes very important with curves, and I noted that a pencil may have helped, however, "using pencil creates a tendency to be timid, either using very faint lines or erasing bad ones. Learning to sketch is the result of continual attempts to reproduce what you see with increasing degrees of accuracy."
