Making the images back and white then Inversing the images is the first most important part for Cyanotypes, I have expermented with Tones and a Sepia tone seemingly works better then exposing the images

Second try at my cyanotypes with a different mix ready to try and print onto Loo Roll.
Due to the weather being extremely cloudy and with having them only exposing for 40 minutes these did not work at all. My prints where not visible even after being washed an dried. Now I know to have a super long exposure in cloudy days. It all about judging the UV intensity appropriately.
