Prepare your workspace by laying down some newspaper or an old tablecloth to protect your surface, and gather all your supplies.
Fill the tray with shaving cream by spraying an even layer into your tray and spreading it out to create a smooth surface.
Add your colors by dropping a few small amounts of food coloring or liquid watercolor across the shaving cream.
Swirl the colors using a popsicle stick to gently blend them, creating a beautiful marbled effect.
Press the paper by taking a piece of cardstock or white paper and pressing it firmly but gently onto the colored shaving cream, ensuring full contact.
Scrape off the shaving cream by carefully lifting your paper and using a popsicle stick to remove the excess.
Let it dry for 5-10 minutes. Once dry, it will be ready to use for cards and gift wrap.
