It is easy to get started and to tie something that will catch fish . I started in the new year and was surprised that the fish took my flies just fine !!

Can't beat the feeling of catching on your own creations .
What I would say though is do as I did ( if you can ) and have someone show you first hand how to dub , tie in hackles , whip finish etc... Failing that get on Utube as there is heaps on there that will help you .
Pick a pattern you will actually fish with and start from there . If you get to a point that you are not happy with a section of the fly then just back track and sort that bit out then go onto finish the fly .
Just keep at over and over and it will all start to fall into place . If you make sure you correct mistakes as you go you will not keep repeating them and before you know it and with out even noticing your flies will be getting neater .
Heads like footballs will soon be a thing of the past
Good luck and make sure you post on here , even if you think it is bad . It is a very good way to get help and have outside eyes looking on seeing where improvements can be made .....
