How do you make Iroquois berry paint?

To make Iroquois berry paint, you'll need berries such as blackberries, raspberries, or pokeweed. First, MASH the berries to extract their juice, then strain the mixture to remove seeds and pulp. You can thicken the juice with natural binders like corn syrup or egg whites if desired. Finally, use the resulting pigment to paint on surfaces like bark, paper, or cloth.
