Oak galls are a potent source of tannins for mordanting in natural dyeing and for dyeing on their own. See my blogpost, The Versatility of Tannins.
These are locally, humanely gathered and are sold in 100g increments. 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
