Jacquards high-quality cotton sateen fabric comes pre-sensitized for cyanotype and ready to use, making sun printing easier than ever before. Just pull the sheet out of the package, place objects on top, expose to light, rinse and dry and you'll have a rich, detailed print.
Here's how it works: when the cyanotype fabric is exposed to sunlight, a chemical reaction occurs. It won't reveal itself, though, until you put the fabric in water. Then it will instantly turn blue!
If handled properly, not exposed early or stored poorly, the treated fabric has a shelf life of at least two years.
