Three basic design planning tools are the sketchbook, the scrapbook, and the ideas book. The sketchbook is a place for designers to keep sketches of their work. These could be anything from skirts to couches and back again. Often, people think of fashion designers when they hear the word “sketchbook” in this context. The scrapbook is a place to keep scraps of fabric or materials that interest the designer.
These are more common among interior designers, furniture designers, and fashion designers. They house scraps or samples for later use, or to refer back to. It allows people to see and live with a fabric before they pick it. The ideas book is a place for inspiration. This could be as simple as a Pinterest board, or as complex as a photo album with captions that has been physically bound.
