Fill one baking dish or dish pan with starch to a depth of about 2 inches; fill the second one with cool water. In custard cups or other small containers, dilute each paint color until it just barely drips from a brush. Then drip colors on top of the starch until the surface of the starch is nearly covered.

Create a pattern in the starch with one or many of your tools. Move the desired tool through the paint in straight lines, at geometric angels, in circles, or in rays. Even if you leave the dots undisturbed to produce a pebble pattern, no two patterns will be the same. Feel free to experiment and be creative!

Hold a card or piece of paper by opposite corners and bend it gently so the paper sags slightly. Lay it gently on top of the paint, but do not allow the paper to sink below the surface. Immediately lift paper back out of the starch. Hold it over the dish and allow the paint to drip off for a few seconds.

Rinse paper in the dish of plain water. Lift paper out of water and allow it to drip for about 15 seconds or until most of the water has dripped off. Lay the paper flat, paint side up, on a work surface to dry.
