The exhibition "Further Evidence: The Art of Natural Dyes" will feature the work of sixteen international artists working with natural dyes. Co-curated by textile artist and dyer Catharine Ellis, who along with Danish textile engineer and chemist Joy Boutrup, will be publishing a long awaited book on the subject and co-teaching at Penland School in 2019. The resurgence of the use of natural dyes in both studio practice and commercial dyeing will be recognized in this exhibition, including works on paper, with ink and pigment, and woven and printed textiles.
