Wind drawing is the process of gathering marks made by leaves moving in the wind. I dip the leaves (still attached to the plant or tree) in different coloured inks or acrylic paints. Sometimes I change the colour after a measured period of time, for example changing the colour after drawing for periods of 10 minutes (eg 'Silver Birch SSW 19mph'.) Other times there are different colours for different wind directions. (eg West Wind. 15 minutes. 10mph)
