 While working on the cardboards I concluded that waves of this magnitude cannot be drawn using a standard method, as their dimensions surpass the physical capability of human being.I resorted to attaching the charcoal that I used for drawing on a long pole and, by standing on tip-toe and gyrating the whole body including carefully thought-out legwork, I negotiated smooth curves.I performed something short of a dance during which the body movement is transmitted into the lines drawn.
