This unpaginated booklet contains 25 recipes for creating dyes from natural materials, such as onion skins, walnut bark and wild coreopsis. The booklet was written by Mitchell County, N.C. native Emma Conley (Mrs. Grover Conley) who taught dyeing and spinning for the Penland Weavers and Potters and the Penland School of Handicrafts (now Penland School of Crafts) from 1935 to 1958. According to the introduction, Conley learned to dye wool as a child, and "the colors and formulas in this pamphlet came from those early experiences and are the ones I have taught at Penland." Meta Lewis assisted Conley with the compilation of the recipes and was responsible for the revised edition that was published several years later.
