The squirt bottle is an invaluable tool. I use any size commercial bottle filled with tap water and spray a fine mist of water over the surface of the wet in-progress painting during the course of the creative process. In the photo above, I am squirting water in the area where I just removed the metal ruler. This process forces any stray bits of wet pulp back into the desired area and ensures a straighter line of newly applied pulp onto the work surface. Sometimes I mix a little acid free glue and/or paper sizing in with the water. This addition allows the new pulp to bond more completely with the drier pulp.
