I have one more crochet conference to attend this year and then I can get back to reviewing '70's crochet books. In the meantime I've read a few 21st century books on yarn and color: The Yarn Book by Penny Walsh (read an excerpt here), and Color: A Natural History of the Palette by Victoria Finlay. (You can read an interview with the author here.)You can also read CPer JD Wolfe's reviews of some '70's crochet books here.
