On a TV show about quilting there was a demonstration of a fabric that was photo-sensitive and you could make images on it by putting objects on it and exposing it to the sun, then dipping it in plain water to bring the image out. I am not talking of dyeing fabric with Setacolor paint. This was a ready-made fabric. It looked grey before treatment and blue after the process. Do you know what it is called and more important, where can I purchase it? Thank you

I am sorry, I don’t know about this product or where to find it. I suggest that you search the website of the channel you saw it on. You could also call Dharma Trading Co. (www.dharmatrading.com) and ask them if they know about it.
best,
