Paste paper is paper painted with paint mixed with paste (wallpaper is a good example). The sheet starts out white. You put it in a bath of water. Then you put it on a piece of plexiglass. You then put down a coat of the paste-paint. Once you have good coverage, you can then drag combs through it, use blocks, fingers, etc.
My favorite method is to cover the paper with one color, then put another cover immediately over that one. Then when you use the implements, the bottom color shows through.
For this paste paper, I used a light brown base and then a black topcoat. I used a faux finishing comb and a rubber stamp of a leaf.
The whole page (about 30x18") took me about 3 minutes to make. You have to work somewhat fast as the paste wants to soak into the paper and dry.
This was some paste paper made by my friends Ray & Jill that was used for the cover of the Ginsberg letter that I printed for Sore Dove. Ray & Jill also did all of the binding. I printed the black piece on the cover.
