One of the most successful tools in my belt is sketching: the ability to cleanly hand-draw wireframes, widgets or even screen designs is an art form which is worth its weight in gold (or Euros). A sketch should be timely in creation, easily understood by the client, and low-fidelity – including only the most pertinent details. It should also be thoughtful and thought-provoking. Sketching, through its hand-crafted nature, should also invite the viewer to participate within the creative process– this is one of the most important aspects of sketching. A sketch should help open up a dialogue that will eventually lead to the creation of finalized, high-fidelity wireframes.
