Sunography—Solar powered photography!
Place any object or transparency on the Sunography paper or fabric, expose it in bright sunlight, and rinse to reveal a rich blue print. Sunography is light sensitive on both sides, to make two sided prints. Made from superior materials, each pack has either 6 sheets of white watercolour paper or 6 squares of cotton fabric in six assorted colours. Prints can be toned yellow or sepia using rinses with common household liquids.
