... how far can I get with just pheasant and chukar feathers, and deer hair?
1. Add copper wire and you can tie the original Sawyer Pheasant Tail nymph. A great baetis nymph.
2. Add strung peacock herl and you can tie American Pheasant Tail nymph, A great all around nymph.
3. Add beads and you can tie bead head Pheasant Tail nymph. Also great all around.
4. Combine the Pheasant Tail nymph body with the right chukar feathers would give you a Chukar and Pheasant Tail soft hackle that would be very useful.
5. Using the peacock herl, copper wire and pheasant or chukar body feathers you can tie the
Carey Special a larger soft hackle style fly.
6. Using the peacock herl for the body, deer hair for the wing and the soft feather fibers from the lower parts of the bird feathers as dubbing for the head. You could tie a simple but effective dry fly caddis imitation.
7. Add some microfibits or bristles from a cheap paint brush for the tails, use the pheasant tail or peacock for the body/head (dubbing would be better for the head, shoot a rabbit or collect a road killed fox). Use the right deer hair and you can tie Comparadun mayfly imitations.
I could fish with just these flies and do pretty well. Add some sparkle yarn and it gets even better.
I know you may need more details, just let us know what you don't know/understand.
