The paragraph is describing London (probably in the 1920s as it's a post-war setting) in a fog: The fog was like a saffron blanket soaked in ice-water. It had hung over London all day and at last was beginning to descend. The sky was yellow as a duster and the rest was a granular black, overprinted in grey, and lightened by occasional slivers of bright fish colour as a policeman turned in his wet cape.
I had bought the Stampers Anonymous Cityscape stamps with a birthday gift - mostly, it has to be said, for the Paris one. But the London one was perfect for this, even though it has a distinctly more modern feel to it with the Gherkin and the London Eye.
The background is a combination of sponging distress inks for that "duster" yellow, and grey Brusho powders. Two photos, because I used splashes of pewter Twinkling H2Os for the slivers of fish colour, and trying to capture both the shine from that and the embossed cityscape was a challenging task.
