Natural dyes are an efficient and creative way to reduce environmental impact and enable the use of non-toxic, low impact solutions. The yarns are boiled in dyes made out of flowers, plants or barks in combination with alum and salt. Alum is a chemical, but it is measured to ensure that it is not damaging for the environment, as the alum soaks into the yarn and doesn’t go in the wastewater. After the boiling, the yarns get dipped in and line dried. This process is repeated multiple times, to deepen the colour.
