Nice enough pattern book, with lots of well-written instructions for varieties of yarns to use for each pattern. Much of the book was written with spinners in mind, but there are detailed instructions for those who aren't "into" spinning and only wanted to see some interesting patterns to knit using specialty yarns.
Sizings are decent, generally up to ~45", and instructions are well-written and thorough. Plus there are lots of information pages and instruction pages at the beginning and ends of the book, with the patterns in the middle. A quiet, decent pattern book, with some good patterns, although none of them especially appealed to me. YMMV.
