Just started meself. Its terribly addictive.
Following advice mostly off the forum I bought
Regents rotateable vice
Ceramic bobbin holder
Hackle pliers
Whip finish tool
Scissors + darning needles (don't need a tackle supplier for these)
Hooks Kamasan B110 and B175 in size 10 and 12
For materials there is a really useful post here
Please help: Fly tying materials
Look at post 12
I bought most of my stuff from MeadowFishery
Meadow Fishery Mickle Trafford Chester Cheshire UK best game fishing tackle shops and stillwater trout fisheries, Fly fishing, spinning rods, reels, fly lines, specialists, rod building, fly tying
The guy there was really helpful.
Craft shops are good and Sally Hansen Hard as nails for varnish from chemists.
I tied some buzzers following Dave Cammiss on You Tube. Lesson 1 shows the basics though he uses half-hitches rather than the whip finish tool. I then tied some floating snails following a pattern from g_bigtrout on the forum. Next up - a Diawl Bach following Dave McPhail on You Tube. Might be a bridge too far this one - I have to go back to work tomorrow.
Nothing I've done is perfect but it mostly looks ok once I've spent several hours working on a pattern.
Best of luck
Dave
