Natural Indigo Dye for Polychromatic Printing & Painting on Cellulose Fabrics for Alumni of Michel’s SFS Indigo Workshops- Day 1 of 2

September 15 @ 9:00 am - 12:00 pm

Michel Garcia, France – Master dyer, phytochemist, botanist, and historian

Thursdays, 15 & 22, September, 2022 | 9:00 – 12:00 PST / 18:00 – 21:00 France
ZOOM Webinar | Slow Fiber Studios ANNEX | 1825 8th St. Berkeley, CA 

2-Day Hybrid Workshop on Sustainable Natural Dye Methods:

OPEN only to Michel’s Natural Dye Workshop Alumni of Slow Fiber Studios (SFS workshops and France tours).

We are repeating Michel’s workshop held on August 18 & 25. Michel will explore alternative types of mordant and thickener, the new methods that Michel derived from his lab experiments. The mordanting and dyeing sequences to achieve polychromatic effects will be short with a special fabric preparation process. Indigo is printed, rinsed, and over dyed in madder (red) or weld (yellow), or both. The popular clay-resist for indigo dyeing Michel introduced in his DVD in 2012 is expanded to a silkscreen application in addition to brush painting and block printing. 

Our international workshops are taught virtually through Zoom Webinar. A small group of fully vaccinated alumni will be welcomed to participate at the SFS Annex in Berkeley. Indigo vats will be available for use. The Annex will have a large monitor and a camera capturing participants’ work to show to the instructor.

Materials you will need

Indigo, Fructose, lime ( Ca(OH)2, lye ( NaOH), aluminum foil, aluminum sulfate, wheat flour, kaolin clay or bentonite, Epsom salt, gum arabic, some natural dyes such as cochineal or madder for red, weld or another yellow dyestuff.

Michel Garcia

In collaboration with Michel Garcia, our workshops on persicaria tinctoria and indigofera suffruticosa, we aim to demystify natural indigo by breaking down the colorant’s diverse extraction possibilities. Sourced from Michel’s life work, he delves into various indigo plant forms of: dried, fresh, compost, powder, paste and paint into our NEW five Hybrid Workshops. Our courses are inspired and modeled from over ten years of the Natural Dye Workshop film productions with emphasis on Michel’s sustainable methods, and extensive ongoing research by Michel Garcia. All Natural Indigo dye used in our workshops are grown and produced sustainably from Stoney Creek Colors, Tennessee, USA.

Michel Garcia is a botanist, chemist, dyer, and naturalist. He is the founder of Couleur Garance (1998) in Lauris, France, and established Le Jardin Conservatoire de Plantes Tinctoriales (Botanical Garden of Dye Plants) in 2000 as a horticultural resource for chemists, natural dye researchers, and botanists. He has been instrumental in revitalizing the natural dye practice in France and abroad.
