I am a keen knitter, having started as a small child in 1970s darkest Sussex, where there wasn't much else to do ;-) Suffice to say I have quite a bit of experience in knitting. I was recently given this book as a present. There are some lovely designs in this book and some less lovely, but the crucial thing for me that can spoil this book as a UK-based knitter is the US terminology. It's not just the needle sizes; it's the differing abbreviations and yarn weights/types etc, and I do find this gets in the way sometimes. As other reviewers have stated, if the author had at least given a generic yarn type throughout for the US yarns so that we could attempt to substitute them, it would have made such a difference. Some patterns do benefit from a better description of yarn type than others - again, as other reviewers have said, this suggests sloppy editing in that the book lacks consistency in this regard. I thought it was just me when I read through a pattern several times very carefully and still couldn't understand it. Now I realise that it was probably just one of the mistakes that have been identified by other reviewers. Another minor point is that several patterns use circular needles, which I personally detest, but of course other knitters may not. In summary, if as a UK knitter you can get past the semantic obstacles, there are some great patterns, but do watch out for errors and be careful/lucky when choosing your yarn!
