A self-published gem! This 60 page paperback journal cum manual covers one woman's experience with natural indigo. This is the fifth edition, published in 1999 and contains lots of useful information on the cultivation and use of Japanese indigo aka dyers knotweed aka persicaria tinctoria aka polygonum tinctorum.
I was lucky to pick up a block of these books and to be able to offer them for sale. They are becoming more and more rare and costly! Grab one while they're still out there!
