In a different approach from the previous chapters, selected prominent designers who are currently practicing were asked to submit a sketch of their choice for inclusion in this book. They were also requested to send a brief biography and a short description of their thoughts while completing the sketch. In most cases, the architects sent biographical materials and a paragraph or two describing the architecture or the impetus for its design. Very few replied with discussion of their thoughts concerning the sketch during the design process. It may have been difficult to remember specific processes; or, perhaps this activity was hard to translate into words, and thus the process remains elusive even to those who constantly use sketches.
