Hi Tiam, keep posting your flies.
I still get alot of stuff online, but most of my feathers ie capes, saddles, hairs ie deer or bucktail etc, i like to go to some of the fly fairs or Game fairs and get a good look at the stuff. I would usually take the feathers out of their packaging to check for fibre lengh and quality. Things like hooks, dubbing, tinsels and thread, and things like that i still get online because you normally cant beat them for value for money. Check out your local tackle shops, Im sure they wont mind you having a look.
Keep practicing you will become great.
John.
