Pre-wet the paper with a brush or spray bottle. The wetter your paper is, the more the colors will bleed.
Rip the pieces into various shapes and place them on the white paper or watercolor paper.
Use a brush and paint water over each piece. You want your tissue paper to be pretty wet so the colors start to “bleed” or soak into the paper.
Overlap the next color slightly and paint water on top of the shapes.
Let dry.
Pull the tissue paper off to reveal your awesome painted paper.
If you have too much white, as we did, just put another layer of tissue paper on top and let it work its magic.
