It didn't do exactly what I expected, which is part of the fun of rust dyeing. So I tried another napkin. This time I aligned the center fold of the napkin with the points of the heart. I liked the result much better, especially the little heart in the center. I set up another one today, but with a different crumple pattern for the edges. I'll keep making these until the cookie sheet collapses into a different shape. hummmmmm......a dinosaur would be interesting!
