I got this book because although an experienced knitter, I had only 1 or 2 types of casting on and off in my repertoire. I do a lot of seamless & Top-down knitting, & the methods I was taught when learning the basics just can't be adapted to suit. This little book has a great range of different methods of each, well illustrated, with handy tips on which is appropriate for different projects, and pluses and minuses of each. My only gripe is in the layout which should be revised for reprints - many of the methods' detailed instructions and photos span 2 pages - surely they could have been laid out to both be visible at the same time? A lot of them need you to turn the page half way through - not easy if you're learning a new method and are holding 2 strands of wool and 5 needles! Other than that it's one of the best books I've got & I'm enjoying trying lots of new methods that are improving the starting/finishing of my projects.
