A one-page column from the Minnesota Weaver's "From Woods & Fields" series answering how to get a deep brown from walnuts. The author explains that the green hull, not the shell, is the best dye source, and compares fresh, dried, and ground-weathered hulls. She gives advice on chopping, soaking, and simmering times, notes that no mordant is needed, and mentions walnut leaves and butternuts as alternative sources.
