Catharine Ellis has been making textiles for over 50 years. Her work most often combines both weaving and dyeing. Currently, her focus is primarily on natural dyeing. She continues to research and develop new applications for the use of natural colorants in her own textiles, for teaching, and her collaborative work with textile researchers. Catharine is the author of Woven Shibori (Interweave Press, 2005). An extensively updated version, released in 2016, focuses on natural dyes. She and Joy Boutrup wrote: The Art and the Science of Natural Dye (Schiffer Press, 2019) as a means of understanding and explaining some of the science behind natural dye processes. Her work has been exhibited in venues worldwide and she has taught internationally.
