As for tying my own, I don't see that happening, ever. I HATE messing with tiny objects, watching part of a fly tying class one time and all I could think was "cripes, what a pain in the rear!"
Didn't you say in your first post you had some little commandos. If you got any around 10 or 12 yrs old they will work as fly tyers. It doesn't cost that much to get a servicable fly tying outfit. Start em off with some Renegades and Gray Hackle Peacocks for the Graying. Then get them tying some Wooly Worms in black, brown, and olive.
I sent you a PM this morning.
