It's about time we saw a book on Celtic knotwork where you can actually construct them, not merely draw them or engrave them. Suzen Millodot's book on Chinese Knots brought that lovely phase of knotting up to date, but her book on Celtic knotting is so long overdue, even late to arrive, on the downside of the Celtic cycle. If you've done macrame and even made a few hemp necklaces but are bored with current projects, its time to go three dimensional with these exquisite shapes. Millodot has her own style of knotting, which not surprisingly, overlaps with Chinese. Her use of the button knot is quite unique to her. I recommend learning the Josephine knot first, described later in the book, first, to get the easiest feel for the over/under rhythm. Then the button knot doesn't seem so difficult. It's merely an unlocked Josephine knot with an extra loop. Her method of pulling up the button knot also seems a doubling of effort. If you use a large hat pin to pull the knot up against, you can place it directly against a bead, rather than having to pull it up and shape it twice. Other than that technical criticism, these projects are feasts for the eyes. If you've done any knotting at all your hands will twitch to get cord between them and make these designs. Millodot's description of tools and methods is clear. The color photographs are stunning and enticing. If you've looked at all those coiled designs on crosses, on manuscripts, on Irish decorative items, now with this book you can pull them out of two dimensions, create them in linen, cotton and satin cord and wear them yourself. This book is a lovely and challenging addition to the current craft books.
