I have found the best green play dough and paint for children that will keep mother's happy and children busy for hours. The organic play dough by over the Rain Dough (love the name!) is 100% plant based coloring, 80% organic ingredients and comes in six kid friendly flavors: Berry Pink Peachy Peach, Cinnamon Brown, Lemony Yellow, Vanilly White and Purpley Grape. I found it on http://www.ecostylebaby.com/. The natural finger paints for kids is derived from vegetable dyes and has no VOC's petro chemicals or other harmful ingredients. Now we just need eco friendly glue!
