I use to teach a book assignment to fourth and fifth grade students. We did
marbling using Crayola acrylic paints mixed with water to create a very
thin consistency. The thinned mixture was dripped into a pan of liquid
blue starch and combed to create terrific designs. (Of course the starch
does not need to be blue) This process was low cost, nontoxic, and doable.
Crayola acrylic paint costs a little more, but they are very versatile.
We had a great time!!! The books were wonderful and the marbling was fun.
