For paste paper, I paint a bunch of solid colors sheets of paper first and then apply the second layer and run the combs through. I use acyclic paint thinned with matte medium for the first layer, second layer I add glazing liquid to slow the drying time down, so I have time to drag the combs through. I don't really like the cooked paste people unusually use for paste paper. I like the intense color I get with acyclic.
I usually work with one color family at a time making several sheets of a color before moving on to the next color family. This one I did with one stencil that I cut out, I use a roller brush and I use the stencil as a negative and then flip the stencil over and print with it as the reverse.
