I came across this book in a well known book chain when I first got involved in the subject of metal thread embroidery. It was very much an impulse purchase after a brief flick through of the pages, but the decision to purchase was one I have thanked every day when I've needed to look something up, or even gain a little inspiration for my next project.
The book is full of stunningly clear pictures of examples of goldwork. As a reference book on the different styles, stitches and mediums used in the technique it is superb. Simple to understand it doesn't overly dress anything up and is the kind of text book I wish existed in all areas of embroidery. So much so that my two friends who have joined me in my hobby have both bought their own copies.
I wouldn't call it a good beginners book to learn from, but I'd happily recommend it to anyone with a growing interest in the technique.
