The patterns are in tiny snippets and bits of charts all through the book. To make the simplest of shawls, it was necessary to chart the whole shawl from beginning to end. Just flipping through the book to the different sections was needlessly confusing and little bits of instructions were strewn hither and yon. If you missed the bit about the transition rows replacing the last few rows of the pattern, you ruined quite a lot of knitting. God forbid that you use a yarn that cannot be frogged. Until I charted a whole shawl, I spent more time ripping out than knitting.
I have knitted for 45 years and done many difficult and intricate patterns. Surely, there was a simpler way to present this very basic design in knitting lace triangles than the over complicated, piecemeal way that was done in this book.
All the above being said, I would still buy the book for the pattern. However, I advise charting the whole shawl design, complete with transition rows, etc., before ever casting on the first stitch.
Added 4 months later: I finished blocking the shawl that I made using this book and have to add to my review and change my rating. I knitted 5 shawls last year and the one made using this book is the most truly magnificent shawl ever. I could use it as a wedding veil, it is so beautiful. Granted figuring out the pattern was difficult, but the result makes me change the book's rating from 1 to 5 stars.
