I am not a native English speaker and I was afraid I could not understand the patterns when I bought this book. My fears were completely unfounded. The book is excellent, I have just finished my second sweater (did a child one and an adult one) using this book and I am perfectly satisfied with the result. You only need to choose the pattern and the rest is in the book. At first, the tables may seem a bit scary, but once you start knitting it's very easy, almost mechanical. I strongly recommend it.
