I'm a fairly experienced knitter of the one-color or color block intarsia vein, rather than a Fair Isle maestro, and what I loved best about this stitch guide is the multitude of reversible stitch patterns offered and shown reverse and obverse. If you knit and love to accumulate guides, stitch dictionaries, pattern books and design-your-own project books, this is a great resource. I find I'm always adapting knitting patterns slightly or significantly to swap out cables, add interesting borders so I can knit edges and body at the same time, what have you.
