I bought this book, with another hand, to give to a friend who likes sewing. I was very disappointed by its content. I myself vocational training in clothing and some boards do not match what I learned and what I bring to my surroundings for easier and better realized seam. so I returned very quickly because I could offer a book that will, for some advice against professional techniques. it seems important to me, and more so if you are a beginner, make good sewing patterns for a good result and not to be discouraged
