This Mordant Monday, I want to share a little bit about my pokeberry dye adventure this past week. Those of you who know me know that I was trained to mordant nearly everything (exception: indigo). Not mordanting something that needs a mordant usually elicits a shocked, silent, but oh-so-judgey raised eyebrow, so this post is a stretch for me. The interesting thing about pokeberries is that it’s possible to get a brilliant color by using wool yarn and white vinegar. No alum mordant is used ...| Botanical Colors
TANNIN A TIMELESS MORDANT Tannins are a bitter and astringent compound found so abundantly in many plants. In food, they serve as the slight pucker in black coffee and tea, and the “oaky” flavor in aged wines. Tannins are used in medicine and for leather tanning. For us, they are the natural dyer’s not-so-secret-weapon to beautiful color. For the natural colorist, tannins provide a rich base for unusual and eye-catching combinations, and they’re particularly effective on plant fib...| Botanical Colors

Kakishibu samples clockwise from top: paste resist by Kentaro Kojima, silk, cotton sashiko thread, cotton with iron, soda ash and kakishibu alone. Natural dyes are fascinating because we can see the history of human curiosity and imagination as it interacts with the natural world. Like, who looked at a hard, green, horribly astringent, inedible persimmon fruit and thought “You know, there’s probably an amazing, insect-repelling, anti-microbial, water-resistant, beautiful color in there if...| Botanical Colors
Thank you to Rachel MacHenry and Gitte Hansen of Contemporary Textile Studio Co-operative for the lovely photos! I taught a one day workshop on middle mordant using Japanese dyes in Toronto on Friday, and had a great time with the students. This was the first time we’d tried the technique using only Japanese dyes that we extracted, and we also had a side trip into kakishibu which didn’t require any mordant, but made a beautiful shade. I’ve written about middle mordanting before: Cathari...| Botanical Colors
We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? Got mordanting questions? Email questions@botanicalcolors.com YOU ASKED: Do you always dye indigo first before overdyeing with another color? Does it make any difference? KATHY ANSWERED: When I was starting out, I was advised to dye with indigo first, rinse, mordant my fabric, and then dye with a mordant color second in order to create any type of compound color when indigo is involved. We largely ag...| Botanical Colors
