I grew up in woods filled with white oak trees. The big beautiful trees would drop their tiny capped seeds each season, covering the ground with a blanket of acorns. As I have experimented more with natural dyeing, I have discovered acorns produce incredible colors in the dye bath. On their own, they produce soft and rich shades of golden brown, and when dipped in a second bath of iron water, they produce stunning shades of gray, from soft and dusty dove to rich charcoal.
