Community Indigo JAM & SOCIAL
Monday 21 October 2019 | Slow Fiber Studios Annex
Slow Fiber Studios you to the third and last Indigo JAM of 2019. On Monday, October 21, we have two very potent indigo vats available for participants to gather, socialize and dye fiber pieces of their latest projects. These all-natural 30 gallon vats are robust, made of a blend of Persicaria tinctoria, Indigofera tinctoria, and Indigofera suffruticosa from Tennessee and California, USA and Oaxaca, Mexico.
Slow Fiber Studios founder Yoshiko I. Wada will provide casual instruction and demonstration at the beginning of the session and will be available to give advice on your latest indigo project. Come and meet fellow dyers over these communal, organic indigo dye vats.
You ae welcome to bring 1-2 pounds of all natural, plant based or silk fabrics or fibers pre-washed, rinsed well, and ready to dye. Let us avoid t-shirts or bulky garments to be courteous to other dyers. Sashiko artists may wish to bring their yarn or cloth to dye, and shibori artisans may wish to bring prepared shibori pieces to dye. The indigo vats will have a higher pH and may be harsh for fine wool fibers.
Regenerative Natural Colorant Manufacturing in the Southeastern U.S.
Thursday 24 October 2019 | Slow Fiber Studios Annex
Sarah Bellos, CEO and Founder of Stony Creek Colors, was a keynote presenter at The North American Indigo Project Colloquium last March, is back in the Bay Area. She will share with us her company’s commitment to working honestly with the natural world and in the process reshaping the future of fashion.
SCC is the first company in the U.S. to grow indigo at a scale usable by the commercial textile industry. The company is expanding to grow, source, and manufacture an array of regional, bio-based dyes that move the color wheel beyond blue. One of their newest products, black walnut paste, is a dye extracted from waste hulls sourced from hulling stations in Tennessee, where the nut is separated out for food use. The company is widely appreciated for introducing alternative crops to farmers in the Southeastern U.S. facing the decreased demand for tobacco.
Join us for an evening with Sarah followed by a potluck dinner. Socialize with the local community and discuss sustainable regional sources of natural dyes.

Natural dyes: A series of FIVE exploratory, focused one-day workshops
Tuesday – Saturday, 10 – 14 September 2019 | Slow Fiber Studios Annex
Thursday 12 September 2019 | Slow Fiber Studios Annex
Catharine Ellis, distinguished textiles artist, educator, and natural dye specialist, taught a comprehensive series of one-day workshops examining natural dyes through five separate specifications. These included dyeing wool with and without mordants, utilizing ‘classic’ tannins such as gall nut and locally available tannin variants, comparing mordant processes, printing with natural dyes, and simultaneous direct application of assorted natural dyes and mordants onto fabric. Students focused on the importance of informed exploration of natural dyes for textile artists who desire a thorough understanding of their processes.

2 Half-Day Workshop by Michel Garcia “Beyond Mordants”: Thursday – Friday, 28 – 29 March 2019 | 9:30-13:00| UC Botanical Garden
Rowland Ricketts: artist talk and indigo dyeing: Friday, 29 March | 18:00-21:00 | San Francisco Museum of Craft & Design in conjunction with the exhibition “Material Domestication”
Slow Fiber Studios and UC Botanical Garden collaborated in presenting the North American Indigo Projects with guest speakers, including world-renowned natural dye expert Michel Garcia from France; Sarah Bellos of Stony Creek Colors, Tennessee; and Rowland Ricketts, Indiana. Their presentations will be followed by a discussion panel with Rebecca Burgess of Fibershed; Kristine Vejar, Berkeley; Craig Wilkinson, Sonoma; Graham Keegan, Los Angeles; and a moderator, Yoshiko Wada, Berkeley. In light of the growing awareness of ecological responsibility—the need to preserve the health of people and the environment, as well as the traceability of production processes—artists, designers, and industries are reviving the use of natural indigo. The colloquium discussed models of using indigo dye in artistic pursuits, community engagement, education all in the intention to learn about revolutionary changes in the industry.
The Slow Fiber Studios Annex initiated a dynamic experience with interactive conversations and exchange of information between invited indigo specialists. This unique crossover facilitated the studio space as a platform to activate expert indigo knowledge, spark imagination and inspire the participants in a wide range of topics concerning indigo. Discussions and demonstrations covered: sukumo (compost), dried indigo leaves, indigo powder and making indigo dye vats.
Presented in our Natural Dye Workshop IV DVD, Michel shared his newly developed printing and painting techniques on cloth. This workshop, he taught two methods how to process insoluble colors such as indigo, annatto, and alkanet for painting. For example, how to extract indigo from dried leaves of indigofera plant family as a dye paste. In addition, Michel covered printing with pagoda tree blossom buds, logwood, and cochineal together on wool. Participants learned to combine and layer various colors together on the the same surface and steam set colors in cloth.

Commonly found in leaves, barks, roots, and fruits of trees, tannins are used to produce wine, leather, and ink. Dyers can use these naturally occurring compounds to produce colors from beige and grey to warm red to dark brown and black, in addition to widening the color palettes for other natural dyes. Take advantage of their unique characteristics to improve colorfastness, bond colors to fibers without using inorganic mineral mordants, and apply photosensitive effects and polymerizing qualities by gaining a deeper understanding of tannins and their diverse applications.

5-7 September 2017
An enduring color throughout human history, indigo blue crosses cultures, from ancient body painting in the British Isles to the saturated robes of Tuareg men in the Sahara. Michel will share his knowledge of botany and chemistry to unlock the mysteries of this widespread dye. This workshop will cover several different reduction vat methods, including fructose, henna, and ferrous vats, as well as applications using fresh leaf indigo grown in Berkeley. In addition Michel will address ethnic indigo traditions including dyeing with multiple types of indigo, such as combining Indigofera tinctoria with Justicia spicigera for a deeper blue, and making Azul Maya (Maya Blue) pigment, a “pre-Columbian nanotechnology” manufactured by ancient Mesoamericans.
Slow Fiber Studios has partnered with the University of California Botanical Garden (UCBG) to extend Michel’s visit with an enriched focus on botanical science. The 34-acre garden hosts over 10,000 types of plants with a mission to develop and maintain a diverse living collection, support teaching and worldwide research in plant biology, further the conservation of plant diversity, and promote public understanding and appreciation of plants and the natural environment.
