Black Walnut Hulls
(Juglans nigra)
Finely ground black walnut hulls locally foraged by Sara here in southwestern Colorado. This tannin rich dye yields a beautiful smokey tan color on cellulose fabrics when used at 10% WOF. When used at stronger WOF ratios black walnut hulls will yield darker grayish browns and for the darkest browns (almost black) you can shift the colors with iron.
Black walnut hulls can also be used to make a tannin bath before treating cellulose fiber with potassium aluminum sulfate (alum) or symplocos mordant. They impart a light tan color on the fibers which can be used as a foundation to dye on. In my book I share some in depth information about tannins in the context of natural dyes.
