Regardless of the final platform — desktop, tablet, mobile — most designers start their explorations on paper. Depending on the designer’s preference, the paper may be bound or unbound, lined or unlined, smooth or ridged. And while the materials may differ, the goal is the same: to quickly explore a variety of concepts.
The designer’s sketching tools haven’t changed much over the years, but the role of sketches has evolved. Instead of rushing to convert them to a more polished form, designers now often share early sketches with clients. Their roughness suggests that the designs aren’t “done,” which encourages feedback and facilitates collaboration.
