If you had to choose a book about sewing, then it is this one (the second choice followed by 'Practical Handbook of sewing, "Hachette)! Complete, clear, accurate and simple. A must !!! Contains no bosses but against it has lots of very detailed drawings by step, full of concrete examples ... Suitable for beginners as well as confirmed seamstresses, this is a real bible and a reference in the matter, that I recommend without hesitation!
