Inspiration can strike at any moment, and for this reason, most designers fill up dozens of notebooks with ideas and drawings. Starting September 1, Princeton Architectural Press has another one to add to your collection inspired by the book, The Architect Says. The wallet-size notebooks feature quotes from notable architects—Le Corbusier, R. Buckminster Fuller, or Cesar Pelli—on the cover. Inside, the gridded paper offers a small canvas for spontaneous designs. Comes in a set of three for $14.95. Available now.
