I saw an artist out here in Oregon that uses coffee as a wash over his ink drawings on watercolor paper. I had been doing watercolor over my ink stippling on watercolor paper. I had some black and white prints on standard card stock, so I decided to experiment what happens if I did a coffee wash over them. the originals looked pretty good, except I didn't tape them down,so they were pretty wrinkled. But, when I took them in to Lazer Quick and had them make copies of the wrinkled experiment they came out FANTASTIC!! Let me give you some directions how to try this: 1. Do a very light(and I mean light)wash over the whole picture. 2. When it dries, take your brush and make puddles of coffee on the piece. let it dry! 3. Repeat puddlings until you are happy with the piece. You'll know when to quit. The final effect are a wonderful marbling. I have also done the same technique with just regular water colors. The secret is to try it on card stock, because it resists the liquid put on it. I doesn't work nearly as well on cold press watercolor paper. It might work well on hot press paper. A question about whether it is archival or not on the originals remains to be seen, but the prints will definitely last if you use archival card stock. Anybody else try this technique??
