MORDANT MONDAY: Weighing Fabric For Mordanting

Amy DuFault — Mon, 08 Jun 2026 20:15:06 +0000

We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? YOU ASKED: I’ve been weighing fabric before and after mordanting lately and noticed that the WOF changes slightly. For the recipes on the site, which weight is relevant for WOF? Post-scour, pre-mordant OR post-scour, post-mordant? KATHY ANSWERED: Our practice is to weigh the fabric prior to scouring and mordanting, so before we start any process on the fabrics. It is the first thing that we do so we can calculate the rest of our formulas during the dye process. YOU ASKED: I basically work 9-5 ... Read more

MORDANT MONDAY: Which Plants Need Mordant?

Amy DuFault — Tue, 19 May 2026 01:48:47 +0000

We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? You Asked: I keep getting mixed answers from people about dyeing with plants from my yard and whether I need to mordant or not when using them. Advice? Kathy Answered! I think some of the confusion arises over what plant we’re talking about. Many plants contain high levels of tannins and these can be used to mordant and dye in one step, rather than using the traditional mordant method with aluminum sulfate or aluminum acetate. Traditional tannin mordants include: Common garden and kitchen tannins ... Read more

MORDANT MONDAY: Mixing Mordants

Amy DuFault — Tue, 12 May 2026 01:27:19 +0000

We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? YOU ASKED: I’m just trying out your new cold mordant aluminum triformate and have mordanted wool, bamboo and cotton After applying tannin to the cellulose I dropped it into the aluminum triformate together with the wool, and the water changed to green. I guess it’s due to the connection between tannin and aluminum? But am I doing something wrong and are the textiles fine for dyeing now? I want to save the mordant bath for further use but now it has a suspicious color. ... Read more

Sunday Visit: Foraging the Forest with Julie Beeler

Cara Piazza — Sun, 03 May 2026 14:00:00 +0000

For Sunday Visit, Botanical Colors sits down with Julie Beeler, the artist and researcher behind Mushroom Color Atlas, to talk about her fall workshop and the surprising, luminous world of fungi-based color. From her base in the Pacific Northwest, Julie has spent years building a living reference of mushroom dyes — cataloging the reds, golds, rusts, greens, blues, and grays that emerge when fiber meets fungus — inviting dyers to look past the forest floor and into an entirely different color story. For those just discovering your work, how would you describe what the Mushroom Color Atlas is — and ... Read more

Mordant Monday: Spotlight on Quebracho Moreno

Cara Piazza — Mon, 20 Apr 2026 14:00:00 +0000

For this Mordant Monday, we are diving into Quebracho Moreno. Quebracho (Schinopsis balansae and Schinopsis lorentzii) is an evergreen tree that grows wild in South America. It grows mainly in Argentina and Paraguay in dense sub-tropical forests which also include a variety of other trees and vegetation. The name is due to its hardness, and comes from two Spanish words, quebrar and hacha, meaning “axe breaker”. In fact, quebracho has been used locally for posts, telegraph poles, bridge timbers, railway ties, paving blocks and for any construction where great durability is desired. Quebracho Moreno (we used to carry a Quebracho Rojo, so we called this one Moreno) ... Read more

Mordant Monday: In the clutches of Cutch

Kathy Hattori — Mon, 13 Apr 2026 18:32:49 +0000

This week’s Mordant Monday explores another well known and important tannin: Cutch. Cutch is a wood dye from Senegalia catechu (formerly Acacia catechu), an acacia species that grows in South and Southeast Asia. The dye is both a colorant, and a traditional medicine. It is also the by-product from the manufacture of “katha”, which is a crystalline substance that is an ingredient in paan or betel nut leaf, which is an Indian mouth freshener and digestive. We’ve never tried paan, but we love cutch for its versatility and deep colors. It’s a sweet-smelling dye and the color yield ranges from ... Read more

Mordant Monday: Chestnut, Fustic, Iron and Indigo

Kathy Hattori — Mon, 06 Apr 2026 20:37:11 +0000

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. Like previous examples, when a tannin is combined with other colors you can get exciting mixes and beautiful color blends that harmonize and are perfect for patchwork, creating gradations and stitching. If you are a yarn person, many of these ... Read more

Sunday Visit: The Eco-Printed Image with Sydni Gause

Cara Piazza — Sun, 05 Apr 2026 15:00:15 +0000

For Sunday Visit, Botanical Colors sits down with Sydni Gause, the natural dyer and fiber artist behind Sydni Gause Silks, to talk about her Eco-Printed Image workshop and the plant stories held inside silk. From her studio in Panama City, Florida, Sydni has developed a pictorial eco printing method that blurs the line between printmaking, painting, and collage, inviting participants to see plant material as more than a single leaf or flower. You developed something you call “The Eco-Printed Image,” a pictorial approach to eco printing. How did this way of working with plants and silk emerge for you over ... Read more

Dye Easter Eggs With Natural Dyes

Cara Piazza — Fri, 27 Mar 2026 18:39:41 +0000

Everyone from kids to adults love to get their hands messy when they dye Easter eggs with natural dyes. This is a fun tutorial for adults and kiddos (parents help, please) to make a little Easter magic. First things first, let’s talk about health & safety: We always recommend working in a very well ventilated area. Although natural dyes are non-toxic, when using fine powders it’s best to wear a mask, and keep the windows open. Be mindful around little ones and pets as you don’t want anything going in mouths that shouldn’t be there. Also, when beginning to set ... Read more
