Cover cardstock completely with ink (sponge, brayer, watercolor brush, etc.). Sprinkle OxiClean on cardstock. Spray water over OxiClean, let sit for about 30 sec. Clean off "crumbs" (easier when paper is dry) Note: Every paper and ink reacts differently Hint: Use bold colors or black for stamping over the background. OxiClean keeps on bleaching your images out a bit.
