Indigo!
We started the Indigo seeds (Persicaria tinctoria, Chijimbia and Grand Prismatic varieties) in mid-Februrary. In July, we harvested and fermented the leaves for a few days, and then alkalized and oxidized the fermented liquid to extract indigo pigment. We then washed the pigment and strained it through coffee filters to dry it. This dried pigment is shelf stable and can be used to make paints and inks, as well as an indigo vat for dyeing.
To make the vat, we combined our pigment with fructose (a reducing agent) and more calcium hydroxide. Once the vat is ready fabric can be dyed in it. Indigo works best with protein fibres like silk, but cotton works good as well. It is a unique dye in that you do not need to mordant cotton beforehand, just scour it. We ran an indigo workshop at Dye Jardin Papillon (see below) explaining the whole process while also giving people the oppourtunity to learn some simple shibori techniques.
