Ria Burns is a sustainable knitwear designer-maker who specialises in working with local wool and natural dyes. She has created thousands of colour samples and dye recipes, and her research into plants and colour is widely recognised. Ria teaches natural dyeing and machine knitting workshops.
A good introduction for those wanting to take their first steps in natural dying with easily accessible plants.
This would be a good book to add to a dye library or an introduction for someone new to the practice and wanting to take a sustainable approach.
