Knitting Brioche is by the self-proclaimed (and very worthy) "Queen of this Brioche Domain", Nancy Marchant.
The website for the book will direct the curious knitter to how to buy the book in the U.S., the U.K., and the Netherlands.
The availability of the book matches its global tone. The book celebrates the Brioche stitch in all of its many forms, several of which were completely new to me. Instructions for making this unusual set of stitches are given for many methods of knitting: English (or American, or Thrown), Continental (or German, or Picked), Eastern Uncrossed and Combination.
Single-color and two-color Brioche knitting are both covered, as well as a host of ways of beginning and ending your project.
If you have a passing interest in this sort of work, this book will prove both useful and invaluable.
