There are a lot of buetiful patters out there on Salmon flies and others,
that I have not tied yet but I have covered the bases pretty well, since I started when I was in High School, bacl in 1962.
My father put a bamboo fly rod in my hand when I was ten and we could go down to a store and buy ten small dry flys for a dollar.
After loosing them to bushes, tree limbs, willows etc. I soon learned as I got older, that buying them might not be the best solution.
I have tied large flys foe King Salmon on the Yuba river, out of Sacramento, Cone head Clousers for Florids waters, Streamers for large Trout in our waters to a small #20, for High Sierra lakes, that hold Golden Trout.
My favorite trout fly on calm waters is the Adams with a Royal Coachman, for when the water has white foam blended in.
At my age I have lots of 20's tied, since a #18 is a lot easier on my old eyes and shaky hands.
However a nymph or "Bug" under a float is a second way to fish on slow days or for warm water pan fish, if you like Crappie and their pals.
Yes I have tied a few in my time.
