More Mordant Experiments

I’m obsessed with using tannin and aluminum sulfate to create different color bases for both natural dyes and indigo. What I love about this technique is that this is a great mordant option and it’s a lot of fun to see the colors develop and take on the subtle differences between the different tannin bases. This time, we’re working with a lightweight, pre-mordanted, organic cotton suitable for stitching and quilting. We mordanted 4 fat quarters, each with a different tannin, and then tried a few dye experiments using Marigold Mix, Madder extract and Indigo. Start with our Mordanted Fat quarter … Read more

Mordant Monday: Middle Mordant Magic

In this week’s Mordant Monday, we discuss Middle Mordant. Middle Mordant is a technique that I learned about from The Art and Science of Natural Dyes. It’s considered to be a Japanese technique and is a simple way to create rich color on silk. Middle mordant uses room temperature dye baths and you can repeat the process until the fabric is the color you want. The purpose of middle mordant is to deepen the depth of shade and most of the examples I’ve seen use silk fabric and alum mordant. There are somewhat similar techniques that old dye books discuss, … Read more

Mordant Monday: Walnut, Madder, Iron and Indigo

Black Walnut Juglans nigra is one of our most interesting tannins and it’s a color that’s native to the North American continent. The entire tree contains color but it is in the green hulls that we find a strong concentration of dark tannins yield light beige to golden brown on cellulose. 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

Dyeing For Dummies: The Mysteries of Walnut Hull Powder

Working for a natural dye guru can give a social media director and consultant (that’s me) an inferiority complex. In fact, when people ask me who I work for and I tell them, Kathy Hattori, a “natural dye guru,” and they say “Oh, you must be really good at dyeing,” all I can do is shrink back a bit and say, “I’ve only dyed once…and um, that was with Kathy.” The look of surprise too many times on people’s faces got me thinking, why WASN’T I trying to learn how to dye? Why was I letting Kathy and all her … Read more
