I mixed weak washes of yellow green, sap green, ruby red and a grey out of ruby red and hookers green. Then I wet the paper thoroughly back and front in a tub and stuck it to a board with gummed tape. Started brushing in the colors quickly but the paper began to dry before I was completely satisfied with the background and before I could add the red. sigh…. Next time I have to try soaking the paper for a few minutes and then taping it.
