A 'pin map' is created by recording all the movements of an individual over the course of a day. The resulting route is then plotted onto a map and laid over a white foam-board background. Pins are pushed through the map to anchor any change in direction taken by the individual and a length of cotton is then led around the route held in place by each pin. Once the cotton is secured, the now redundant map is cut away leaving only a plain white background, the web of cotton and the pins.
