20 December 2010 Drawing is important but any professional should be able to fully explain their intentions without the need of visual aid. Some people will, and have felt insulted when shown a drawing to describe a process and we simply can’t tell them to change the mentality. Sketching is important but like Luke Jones quoted in his comment, sketchbooks are about thinking through processes. Unless it’s a really big or complex project I would never show clients my wireframing. Always go with a solid design.
