Firstly, I'm NOT the best fly tyer in the world - maybe the second-best but definitely not the best (and if you believe that then you'll believe anything) 
The idea of this section is to show you some of the saltwater flies I tie and use around the Dorset coast. Probably none of my flies are 'true' to the original pattern as I've adapted them to match both our local conditions and my fly tying ability 
A couple of the flies I can't really put a name to as they don't match a particular pattern so I've called them after the species I've tied them to catch (and sometimes actually succeeded), and that's the joy of fly tying - not slavishly following established patterns but having a play with the scraps in the bottom of your fly tying box to make something that looks good and hopefully works!
Believe me - the first time you catch a Bass, etc on a fly you've tied then you'll be totally addicted
Be prepared for a pastime that will consume most of the rest of your waking hours (unless like me you dream about them too
).
You don't need a load of expensive tools for this; a fly vice is really an essential for tying (get them for between £5 and £150) as is a good, sharp pair of nail scissors. Bobbin holders make life so much easier and a whipping tool can be useful until you get experienced. Occasionally you'll need hackle pliers and a pair of tweezers but that's about it...
There are plenty of videos, etc about tying flies and a quick search of You Tube and Google will give you plenty of information. Don't be disheartened if your flies are crooked or tatty when you first start tying
It's said that the first 20 or thirty flies that people tie are usually thrown away (lots more than that in my case)
Start with simpler patterns on larger hooks just to get you familiar with the basics - one of the best beginners flies is the Blonde Fly or the Clouser. Easy to tie and deadly to fish 
Have fun !!!
