raw corn-on-the-cob
stiff wires (a couple of inches long)
acrylic fabric paint
cotton fabric
Break corncob into 2-inch pieces. Stick a wire into each end, forming a handle. Pour a puddle of paint into something flat, like a pie tin or lid. Roll the corn through the paint, then onto the fabric, in whatever design you like. Let dry before changing colors. Heat set according to direction on paint if the item is to be washed.
