My example faded away, but was just cyanotype chemistry poured on xisting older concrete sidewalk, then coverred to dry. A big negative was used. A garden hose was used to "develop" the image.

The shame of it all is that I had so little interest in my experiment that I never photographed it. So all that remains is a memory.
