Picking up downed evergreen branches of pine & spruce trees not only cleans up your yard, but can be repurposed into some beautiful colors in your dye pot. The natural tannin in the branches will give you a beige color on textile, but with the addition of all-in-one mordant of alum & iron water, you can achieve olive greens and rich browns as well. This tutorial will show you how to brew dye from foraged pine & spruce branches and expand your palette with an all-in-one mordant technique, plus the resulting color swatch samples (cotton & silk).
