BRIOCHE CHIC is an excellent reference book on brioche knitting that includes an uneven collection of 22 garment designs. There are two methods of brioche knitting: (1) the simple alternating "knit one in the row below" method that produces the well-known, stretchy "fisherman's rib"; and (2) the more complicated alternating "slipped stitch with yarnover" method that the book relies on.
I very much like the designer's explanation of why a knitter might want to use brioche knitting: "The depth of texture and stunning color effects made possible through brioche's stitch manipulation make these pieces worth the time. In colorwork, handling two colors of yarn per row can be easier, since you are working each color one at a time before returning to the beginning to work the second color, much like mosaic knitting. With cables, colorwork, and other texture patterns, the work is often reversible . . . ."
Most of the garment designs are rather plain, but allow knitters to practice the brioche knitting techniques. Most patterns are written for multiple sizes, and call for worsted, DK, or sportweight yarn (and medium-size needles appropriate to the yarns and brioche knitting structure). There are patterns for brioche-knit shawls, hats, mittens, scarves, and sweaters.
A few designs really stand out for me, as garments that I like a lot, and would enjoy knitting. These are the Lattice-Edged Cardigan (an open-front dolman cardigan with directionally knit garter stitch body and wavy brioche stitch cables at the cuffs and fronts that also form a shawl collar); the Cowl-Neck Pullover (the dolman pullover with flat-shaped brioche cables shown in the book cover photo); and the Smocked Blouse (a cap-sleeve stockinette tee with brioche cables along the scoop neckline which ultimately join up with a simple smocking stitch across the front to make a textural bib).
The greatest weakness of this book is the one page that explains how to knit the three basic brioche stitches (slip one, yarnover; brioche knit; brioche purl) that are used in the brioche knitting method used in the book (see the page titled "The Structure of Brioche"). A knitter must read the written explanations carefully, and also study the accompanying line drawings closely, in order to fully understand this brioche method. But as long as a knitter has the skills to reproduce the drawings on her/his own needles, then she/he should be able to knit everything in the book. Brioche knitting isn't particularly difficult, but it's probably best attempted by those with at least intermediate knitting skills.
As a knitter's bookshelf reference, there are step-by-step instructions, with accompanying line drawings and blown-up photos of finished swatches, for each of the following:
---Basic brioche cast-ons and bind-offs (long-tail; Italian tubular; alternate cable; two standard bind-offs; tubular; k2tog bind-off)
---Brioche increases and decreases for shaping (two basic increases; five basic decreases; two advanced decreases)
---Brioche charting for one-color and two-color brioche, in rounds and in rows
---Brioche cables (traditional twisted cables; flat-shaped cables)
---Two-color brioche cast-ons and bind-offs
---Two-color brioche stitch patterns (brioche rib, brioche stockinette)
---Other brioche methods (fisherman's rib; half fisherman's rib; garter brioche stitch; knit-one-below method for two-color brioche stripe)
