Oak galls are a potent source of tannins for mordanting in natural dyeing and for dyeing on their own. they are an excellent mordant for plants fibers and act as a subtle dye for animal fibers. See my blogpost, The Versatility of Tannins.
These are locally, humanely gathered and are sold in 100g weights. 10 grams/ 100 grams of fiber is plenty for mordanting. A higher ratio is recommended for dyeing.
1 unit = 100 grams (3.5oz) of whole oak galls
