Sunography textile kit

Place any object, slide, x-ray, or other surface printed on a transparency on the fabric. Expose it to direct sunlight for a few minutes and rinse the fabric to reveal the blue. The fabric is light sensitive on both sides. Made from high quality materials, each kit contains 6 squares of fabric ready for display. Prints can be tinted yellow or sepia by adding a little detergent when rinsing. This type of print (cyanotype) dates back to 1842 and was popularized by Anne Atkin, one of the first women photographers. Size : 15 cm x 15 cm.
