Sun Art paper is a cyanotype. Ultraviolet light from the sun affects the color pigments in the paper, allowing images of flowers, buttons, or other objects from around the house or found in nature to be captured in the paper. This 4x4 made-in-the-USA kit includes 15 pieces of light sensitive paper, an acrylic panel protected by a Blue masking, and instructions. You must remove the blue masking from both sides of the acrylic panel before use. You can arrange objects on top of the panel or below on windy days. You can also use a wide tip dry erase marker on the surface of the panel to produce text on the paper. After exposure, the paper will continue to darken for several hours after being rinsed. Once dry, the image can be flattened under a heavy book for a day or two to eliminate curling. Try experimenting by painting on the acrylic panel with sunscreen to see the difference between SPF's. If it's raining and you would still like to use your Sun Art paper, you can expose it to a bright indoor light, though it will take longer to darken. Objects not included.
