Natural Indigo for Polychromatic Printing and Painting on Cellulose Fabrics for Alumni of All Michel Garcia’s Natural Dye Workshops – Day 2 of 2

September 22, 2022 @ 09:00

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 to Alumni of All Michel’s Natural Dye Workshops.

This new indigo workshop is open to alumni of all Michel Garcia’s natural dye and indigo workshops held at various venues. In this workshop, Michel will explore alternative types of mordant and thickener, new methods developed from his lab experiments. They are different from the mordant printing taught in DVD1: Colors of Provence Using Sustainable Methods. The mordanting and dyeing sequences in this workshop are shorter, with a special fabric preparation process. After the fabric is dyed and printed with a specific preparation, it is dried and printed in indigo, rinsed, and overdyed in madder (red) or weld (yellow), or both. 

In 2022, Michel focuses his teachings on indigo dyers and natural dye enthusiasts who wish to continue honing their skills and exploring creative possibilities. Students will learn a unique artisan method that will heighten their ability to create their own hand-dyed textile masterpieces. 

Our international workshops are taught virtually and will be streamed 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.

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.
