The Guild is to run flytying courses starting in January 2015 (see the Programme page on this website). If you are a beginner or need to brush up your techniques, there are lots of books out there which will help, but do have a look at this one (available from Gloucester Library if you can’t find it elsewhere):
Fly Tying for Beginners by Peter Gathercole
ISBN 1-84513-118-5 published 2005 by Aurum Press Ltd
It comes in a small spring-bound book approx. 6” x 8” and has sections on tools & materials and a large section on Core Techniques such as spinning deer hair, dubbing, parachute hackles, etc, then clear descriptions of how to tie 50 top flies including nymphs, wet and dry flies, streamers and hairwings, clearly illustrated with excellent photographs. There is also a Fly Directory showing all the 50 flies so you can spot which one you’d like to tie at a glance.
Have a go!
