The listing, How to: Sun Paint book *only* by Klutz has ended.
This is a fun book my kids and I did with sun painting. It is loaded with great ideas. The illustrations are wonderful. You just have to purchase the supplies separately at any craft store like Michael's.
Information on sun painting
The easiest method of sun printing is actually sun painting, not dyeing. You saturate fabric with any transparent fabric paint, arrange objects on the damp fabric, then expose the assemblage to the sun or any hot lamp. It is actually the infrared light (radiant heat) which does the trick. It is not the ultraviolet in the light which does the work, as is sometimes claimed, but instead infrared, so a halogen lamp is more suitable than a fluorescent sun lamp. Exposed areas dry first, in the hot light; the exposed fabric, as it dries, sucks additional wet dye out from under whatever you have placed on top of the fabric. The result is lighter-colored 'shadows' wherever you placed the masking objects. The color is deeper where the light from the sun, or the hot lamp, was able to reach. This procedure has been widely popularized for use with Seta Color brand fabric paint; for example, see the Klutz book of Sun Painting, entitled Sun Paint. However, the same technique can be used with other brands of thin, transparent fabric paint, as well; for example, PRO Chemical & Dye provides instructions for "Sun Printing using PROfab Textile Paints", and Jacquard includes sun printing in their online instructions page for Dye-Na-Flow fabric paint. Sun painting is a highly suitable project for children and beginners.
