Book Review: Gene Shepherd's 'Prepared To Dye'

I bought this recently and, in spite of my bull-at-a-gate attitude to everything, actually read it (most of it anyway). It is excellent! I had no understanding of the why's and wherefore's of dyeing fabric and have found it very, practically useful immediately. I did have a good section on dyeing in another book, a very old (and wonderful) book, however, Gene Shepherd's 'Prepared To Dye' goes into the middle of things and explains why as well as how.
An excellent book! I will be using methods found there this weekend, to reduce the colour intensity of previous efforts.
