This beautiful book gives a clear and approachable introduction to the Chinese tradition of decorative knotting. It starts with a few pages of the craft's history in China, and includes some gorgeous examples sure to inspire just about any reader. How-to comes next, with a discussion of the tools (few and inexpensive) and materials of this technique. After the basics, another section shows "compound" knots, built from repetitions and recursions of the elementary techniques. Chen ends this book with a gallery section. This presents a range of attractive and practical applications, not just lovely works in themselves but inspiration to the budding knotter.
You can approach the craft as a unique body of knowledge in itself, or as a complement to other techniques. Either way, this warrants at least a little of any crafter's time - or, in the author's case, a lifetime of fascination.
