Book excerpt: As a student of interior design, interior architecture, or home and office decoration, learning how to plan the layout of an interior space is an important course in the study of interior design. Being an essential facet of the interior design course, space planning requires a sketchbook cum journal that is created specifically for this purpose. This design drawing book, with title blocks and notes sections, is a classroom tool that should be a part of a creative arts student's school supplies. It is a tool that can be used to illustrate design concepts and ideas from the early stages of the course through to its completion.
