This book is really disappointing to me. I have been knitting for 20+ years, I have been teaching for 4+ years, I am a big fan of one-piece sweaters and in fact favor the top down approach (as opposed to bottom up) - but I know this book will confuse & frustrate a lot of knitters trying to make a nice sweater. I've read through it twice so far and I have found several things wrong or unappealing, from styling (a matter of opinion) to technique (a matter of experience) to plain ol' math (simple fact).
1) Math errors in the initial, basic explanations (30/2 = 10?) which make it hard to follow.
I also found one reference to a "psso" (pass slipped st over) where there isn't a preceding st that was slipped - any knitter, novice or experienced, will be brought up short at that one. I think what they meant, and what they should have written, was "bind off one st".
2a) The only decrease technique used is k2tog; nowhere have I found a mention of using paired decreases (i.e. using left-leaning decs, such as ssk or skp, to mirror the right-leaning k2tog). This is a relatively basic technique.
2b) The author apparently has not learned how to correctly do short rows, and she makes it sound like a difficult and tricky technique to explain why she doesn't use it. This is in fact the most elegant shaping solution for issues such as raising the back neck of a sweater, or adding extra fullness required at the bust. I have successfully taught many knitters the short-row technique in a single 2-hour class session.
3) The method the author suggests to get around doing short rows is to place (a LOT of) additional fabric on the front of the sweater. This may be fine for busty gals - I personally wouldn't know! - but makes for a poor-fitting sweater for anyone else. You will have to make the yoke much longer in order for the back of the sweater to be big enough across, and you will end up with wads of extra fabric under the arms. Take a close look at the pics and you'll see almost every one shows a model with her arms down, or else with baggy underarms.
I also thought the layout of the book in 3 columns made for choppy sentences which made the instructions that much harder to follow.
The saving graces are:
1) The section on collars looks pretty complete and is nice to show the variety of collar types (though I am leery of the instructions at this point).
2) A nice use of details, such as bows and other embellishments, plus some good examples of yarn combinations.
Too many knitting publishers are now trying to take advantage of the popularity of the sport, and are flooding the market with substandard books. No repercussions occur to them - but I imagine the poor knitter who spends hours of work, and cries tears of frustration - and it makes me angry.
You're far better off with Barbara Walker's old standard - it doesn't have glossy pictures but the information is the best.
