There often are times when I notice my pencil is suddenly short. This happens most when I am drawing a rough sketch of a plan or cross-section, or contemplating details. Landscape design begins with understating and sorting out the given conditions, background, environment, etc. of the project and envisioning an image of how the space will transform, which often has no scale. Relying on experience, I try to replicate the imagined space in appropriate dimensions by drawing layers of lines on a tracing paper, from which I find the exact ones to include in the drawing, and before you know it, my pencil grows quite short.
