Mordant Monday: Spotlight on Quebracho Moreno

Today in our tannin series we move on to Quebracho Moreno. Quebracho (Schinopsis balansae and Schinopsis lorentzii) is an evergreen tree that grows wild in South America.

This week’s Mordant Monday focuses on Chestnut. We used Chestnut extract in our gradation and absolutely loved the combination of Chestnut, Fustic and Iron with Indigo. This gradation is slightly different than our previous experiments. This time I did not overdye with a warm shade like Madder, to get corals and pinks. I wanted to focus on green and blue.

If you are a yarn person, many of these … Read more

On wool, black walnut really shines and makes a rich brown shade. Walnut Hull Powder from black walnut (Juglans nigra) is a common source of brown dye throughout North America. The fleshy hulls are full of tannin, juglone and other pigments and are the primary source of the dye. … Read more
