This is done on white fabric with Pebeo Setacolor Soleil paint. I put a quilting grid stencil over top of the painted fabric and then put it out in the sun. The object on the right was a potato masher.
The other 2 pieces I’ve brought in from outside didn’t print as well. Well, one of them had sprinkles of salt on it, and the salt didn’t do much. I didn’t have any rock salt, which would have worked better. Even without any printing showing up, the fabric is much prettier than when it started….
I’ve got a piece of Tyvek out there still, plus some other pieces. Even if they don’t turn out all that great, it’s definitely given me some ideas for future experimentation!
