Thoroughly revised and updated for the 21st-century tyer, this book contains chapters that cover the best tools and materials and what makes them so, subtle analyses of hooks, hackle, furs and colour, thread work, making proper weaves and wraps, fur bodies, double split wings, dubbing methods, using a parachute gallows tool and much more. The book goes on to analyse streamside problems and their fly-tying solutions, including matching insect hatches.
