Use drops of food coloring, on shaving cream. Swirl (gently to still keep colors vibrant). Carefully lift the paper up. Using a straight edge (We used a dish scraper), scrape of the shaving cream. Revealed underneath will be gorgeous marbled paper. Allow to dry.
Shaving Cream and Paint. This worked great...made some pretty rainbows! You can use a metal spatula to scrape off the shave cream. Unscented is best as the pictures will smell for several days. Great way to use up some of my excess shave cream I got from couponing a while back!
