Welcome to my backwards post!
Although I have not yet purchased India Flint's book Eco Colour (nor have I purchased her follow-up - Second Skin); I did attend a talk by her last year, and from what I remember, it seemed the process was as follows: grab some plants, roll 'em up tight in cotton, silk, wool or other natural fibers, cook 'em, and let them hang around for awhile. Open them up and be amazed and astounded by their beauty!
