My first fly was tied out of dog hair, yes DOG hair.
We had this German sheperd when I was 15 and she would shed like crazy. So I would take some of the dog hair and tie a fly that looked like a Lefty Deceiver. I tied it on a regular bait hook with sewing thred and painted eyes and finished it off with my mothers clear finger nail polish.

I fished folsom lake in the evenings in the spring and summer.
Between Dike 8 and Mormon Island.
In the spring the Small Mouth would be the first to come into the shallow water off the points.
I still have my first fly rod a Fenwick 7 1/2 foot 6wt bought in 1973 or 1974.
Take care
