Many years ago I had the good fortune of being guided by Tim and also attending his weekly fly-tying sessions.The many things I learned then have been put into practice ever since.
This eBook is well written, very informative and easy to follow. The video links are an excellent way of illustrating the topics being covered. Both newcomers to the sport and more experienced fly-tyers will benefit greatly from this book which contains a myriad of tips and techniques which will improve the reader's own tying methods.
I highly recommend it and look forward to reading his other publications.
