Much of the creativity in the world of fly tying is coming from the exploration and use of synthetic materials. Whether it's closed-cell foam for that high-floating grasshopper, a wing made out of dish-packing material, or a nymph body fashioned from latex, synthetics are the new thing. Yet, no one has put together a useful guide showing how to tie with synthetics. Now, David Klausmeyer brings his brilliant photography and his written step-by-step instructions to bear, and shows how to blend these new materials with traditional ingredients to create a fly box full of practical, real-world fish-catching flies. These flies are guaranteed to catch trout!
