Hi Obi1,
Tying in a golden pheasant tippet tail is not the easiest skill to master. I would suggest you begin with a simple black spider:
Materials:
Hook: size 10 down eyed wet fly hook
Body: black tying thread
Hackle: a black hen hackle with a fine stalk.
Method:
Holding the thread spool in a bobbin holder, tie in the thread about 2 mm from the eye of the hook, wind (away from you over the top of the hook) back along the hook shank, in touching turns, to a point level with the hook barb (cutting off the tag end before reaching the last couple of turns), and back again to the starting point. The body should be smooth with no overlapping turns.
Strip the fluffy hackle fibres from the base of a black hen hackle. Lay the hackle along the top of the hook with the stalk lying forward over the hook eye and the hackle fibres curving downwards. Secure the hackle stalk with two or three touching turns of thread, wound forward towards the hook eye. Cut off the surplus length of hackle stalk with fine pointed scissors. Allow the bobbin holder to hang straight down keeping the thread under slight tension.
With the tip of the hackle gripped in your hackle pliers, wind three full turns of the hackle round the hook towards the hook eye, winding in the same direction as the thread. Keep the hackle pliers under slight tension while you catch and tie the last turn of hackle in with two turns of tying thread. Carefully cut off the surplus hackle tip. Wind the tying thread firmly through the hackle two turns back and two turns forward again towards the hook eye, being careful to avoid catching and tying down individual hackle fibres.
Form a small neat head using a whip finish, while holding back the hackle fibres at the desired angle, slightly backward of the vertical. I prefer to do this using the first and second finger of the right hand, rather than a whip finish tool. For an illustration, see:
Whip Finish
Apply a drop of varnish to the head using a needle, being careful to avoid getting varnish on the hackle.
It is worth spending some time perfecting your whip finish before progressing to more complicated flies.
