black walnut husks, ground
Black walnuts are obtained from the bark of the black walnut tree and the fruits green husks. The hulls of the black walnut have tannin in them, therefore a mordant is not necessary. Black walnuts create a lovely earth tone brown and can be shifted to a darker brown with an iron modifier or a concentrated dye bath. Use at 75%-100% WOF. Sold by the ounce.
