Red cabbage is a natural way to create purple dye for your textile and craft projects by simply chopping it up and throwing it in a pot of simmering water. The leftover 'soup' will be a vibrant dye that colors your fiber shades of lilac and lavender to deeper violet tones depending on your textile. This tutorial will show you how to brew dye from red cabbage, as well as the resulting color swatch samples (cotton & silk) with various mordants.
