After meeting the client, learning his figure and his taste. After I get an idea of what he/she wants - Drawing is the next step. I also encourage my clients to draw in basic lines; their own idea, assuming that all can draw more or less. Your drawing helps in many cases to understand better. I draw whenever I can, using it also as a trigger for new designs. I would say it is a way to transmit your idea with the minimum explanation. It is best to avoid mistakes in planning, once you got all measurements and details included in the drawing itself. Nevertheless, Made to Measure is always opened to changes; further modifying and improvement are necessary to get to perfection.
