The TRACE Sketchbook is an architect-designed tool for ideation and creative development. Architects, artists, designers, engineers and other creative minded professionals will love using the vellum trace paper to produce and refine design ideas. The A5 size (5.8” x 8.3”) fits nicely in the hand and 75 pages is the perfect length to keep your work organized and concise without getting bulky. Subtle white ink reticles are printed on the trace paper at a quarter-inch scale (1/4" scale) to allow for simple design scaling that will not dominate your sketch. The cover stock is a thick 650g chipboard to stand up to wear in your bag. The double ring spiral binding is placed at the top of the sketchbook which allows it to be open in a landscape orientation. Use it in portrait "steno style" without worrying about the position of the rings, making it perfect for accommodating both lefties and righties. (Pro Tip: Start drawing in the back of the book and work towards the front, tracing over your previous sketches as you go.) Designed in collaboration with 30X40 Design Workshop.
