With a double-page spread devoted to each pattern, featuring step-by-step instructions in full colour, and ring bound so that it will lie flat on the bench or table top beside the fly-tying vice, this is a reference book for anglers who wish to tie their own versions of the most successful patterns in current use. The book starts with an introduction to fly-tying basics, material, equipment and techniques. The flies themselves are divided into five categories, Dry Flies, Nymphs and Bugs, Wet Flies, Streamers and Hairwings and covers patterns that have a proven record of success in catching rainbow and brown trout, sea trout, salmon and grayling in rivers and lakes throughout the world. On each spread there is a key indicating which species the fly is designed to attract, a brief description of when and how it should be used, a full-colour photograph of the finished fly indicating the materials used for body, rib, hackle, and so on, the range of hook sizes for which the pattern is suitable and, on the facing page, step-by-step instructions for tying.
