This book explains things really well and is very English, unlike most of the other books out there. What disappointed me was that there wasn't much in it that I actually wanted to make. Even in the professional pictures some of the stuff looks ill fitting and frankly a bit rubbish (fancy knitting your boyfriend a woolly necktie anyone??), also there are some basic layout mistakes where it's easy to follow the wrong steps when taking a pattern from one page to the next because the description of where to go next is just plain wrong.
However in terms of the actual techniques taught though it's fine and gives very clear explanations - what I've ended up doing is making things from the patterns in the Chicks With Sticks guide but using the explanations from here - the techniques taught are basically the same.
