This pattern has many many variations but this original still stands above the rest in its simplicity turning fish on.
1 x Cock Pheasant tail feather
Fine copper wire
A hook sizes 12 to 18
Tying an original pheasant tail nymph
If possible, Load a bobbin with your spool of fine copper wire as this will make the tying easier.
Come a couple of mm back from the eye of the hook.
Start threading on your wire as you would silk and build a thorax of wir.
Now tight turns head to the back of the hook.
Take 4 to 6 fibers of the pheasant tail and tie in the tail.
Now twist the fibers and wire together to make a mixed rope and wrap the body forward.
When at the front, behind the eye area, release the fibers from the wire and make a wire wrap to secure the fibers.
Take the wire back in a wide wrap to the back of the thorax
Now send the fibers backward to cover the thorax and make one wrap wit the wire to secure it.
NOTE: You can finish here with a half hitch and trim the fibers as this was a basic variant Frank made if the fibers are short.
Tack the wire forward in a wide wrap and take the fibers towards the eye. Secure with a wire wrap and a couple pf half hitches to secure.
A dab of varnish on the copper wire head will make it last longer while fishing but you do not have to do this
A stroke of genius by Frank to make a simple fly, with is flashes of copper, attract fish like no other.
Wishing you tight lines
