This is what I did with paneling in two customers homes.
This one is done with two colors, glaze and water. Two seperate views of the room at the house warming party they had.
In this image you can see the room had a tile ceiling, and I also sponge painted it an the dining room(next to it).
The other one I cannot find the image of, but what I did was take the sand paint (similar looking to plaster), and rolled it on the walls after I mixed it with a taupe color latex. then I did a smll amount of controlled paint spatters of two complimentary colors of latex to match the other room decor.
Hope that helps.
