Yes, I did. It is the Photoformulary "New" Cyanotype Kit that I used and followed the directions accurately. "Nuts!" I will purchase another kit and try again. I think I will keep the stock jar in a larger outer container with some small dessicant packets to see if this helps.

Thanks for confirming that the solution should have a comparatively long shelf-life.
