Wool and silk, whether in fiber form, as yarn, or as fabric, can be easily and permanently dyed with acid dyes that are lightfast. Using the primary colors yellow, pink, blue, and black from the company Ashford as examples, Gabriele Breuer's book precisely describes the necessary steps: preparing the raw material, creating dye solutions, intentionally mixing shades, various dyeing and painting techniques, as well as the quick and straightforward fixation of the dyeing in a microwave. With the help of numerous detailed mixing recipes, even beginners have access to an extensive color palette: all the colors of the rainbow, pastel shades, muted earth tones – the possibilities are endless. Further dyeing projects encourage personal experimentation with different materials.
