Gather materials Spread an even layer of shaving cream, about 1inch thick, on the bottom of the container. Add drops of food coloring in desired areas. Swirl the colors using the back end of the paintbrush. Not too much so the colors mix completely together. Lay the paper directly over the shaving cream and press until the face of the paper is completely covered in shaving cream. Take the paper out of the shaving cream and wait a few minutes before the next step. Scrape off the layer of shaving cream with the strait edge or ruler. Finished Product
