The easiest way to make large scale sun prints! Pretreated cotton sateen fabric is light-sensitive and comes ready-to-use for sun printing. Harness the power of the sun to make detailed prints from virtually any object that casts a shadow: tools, toys, plants, leaves, stones, sand, string, lace, etc. Simply place the object on the sensitized surface and expose to sunlight (UV). Use a digitally-printed photographic negative instead of an object to create full-resolution photographs on paper or fabric. Great for photographers, mixed media artists, printmakers, quilters, kids and more, the cyanotype process is easy, forgiving, quick, magical and fun. Capture the nuance of every shadow, a great group activity for any age! This package contains one piece 60x84 inch pretreated cotton fabric. Made in the USA.
