March 5-7, 2017 - Woven Shibori and the Organic Indigo Vat

Arizona Desert Weavers and Spinners Guild, Phoenix, AZ

This is a workshop for weavers who are interested in transforming their work through dyeing. Weaving will be done with cotton or other cellulose fiber and all dyeing will be done with indigo. The class will build organic indigo vats, using fructose, henna, or iron as reduction agents. Students will learn how to use these vats and maintain them.

Looms will be prepared for woven shibori, according to instructions provided. Emphasis will be place on experimenting with patterns and understanding structural possibilities on 4 or 8 shafts. Students will be encouraged to sample but it will be possible to complete a small product such as a scarf or woven runner.

April 21, 2017 - Mixing Colors with Natural Dye

Cloth Fiber Workshop, Asheville, NC

Natural dye colors can be mixed in the pot, or by using after-baths. The class will experiment with controlled shades and gradations of color on wool. At the end of the day, students will have samples and records of several different color gradations, including the use of indigo.

April 22, 2017 - Middle Mordant on Silk

Cloth Fiber Workshop, Asheville, NC

This class will introduce the Japanese approach of applying the mordant in the middle of the dyeing process, rather than using a pre-mordant. We will also learn to safely use iron on silk in order to shift color. Participants will dye silk scarf lengths with 3 different dyes.

September 18,19, 2017 - Dyeing and Printing on Cotton with Natural Dyes (with Joy Boutrup)

8th ETN Conference, Borås, Sweden

This class will explore a variety of techniques used for printing on cotton with natural dyes: mordant printing, selective use of tannin, mordant discharge, indigo resist dyeing, indigo discharge printing, and direct application of dye. The goal is to explore the tools required to create a rich layered surface of natural colors, inspired by the naturally dyed and printed fabrics of India.

March 27-30, 2018 - Natural Dye Study

This class will be an in-depth look at natural dye processes for both cellulose and silk with an emphasis on sustainable practice.
