Just like tie-dying, except with paper. Draw on paper with crayons or not, then dip in one color at a time and then a second color for teaching color blending. Then maybe a third color for some fantastic multi-color effects. The kit includes 4 (red, blue, yellow and green) washable non-toxic dyes that make 1/2 quart each, 50 sheets 9 x 12 inch Dippity Paper, and "How To's".
