Take a length of bucktail about 1.5 to 2 times the length of the hookshank. Hold the tips with you left hand and gently stroke any fluff / underfur from the other end with your thumb and forefinger. This will make tying in a lot easier.
Lay the bucktail onto the hookshank and lightly secure it with thread. Try not to pull the thread too tight at this stage, it could flare. About 1/3 length of the hookshank from the eye, cut the ends of the bucktail into a taper and secure down with thread. Run the thread back down the hookshank and back again to create an even body and secure the bucktail. Leave the thread around 1/3 length of the hookshank from the eye.
Leaving the bobbin dangling, take a length of pearl crystal flash and pass it around the thread, lift it up onto the hookshank in a loop, the thread should just lift with it and trap it in place. This should then allow you to perform a couple of wraps onto the top of the hookshank to secure it.
Do exactly the same for a length of red / hot orange crystal flash. You should now have two pearl crystal flash and two red / hot orange crystal flash of equal length tied onto the top of the hookshank.
Pull the 4 strands back towards the tail and secure them with thread so they lay dead centre on top of the bucktail. Return the thread about 1/3 way up the hookshank, this is where the orange floss will be tied in.
Take some orange floss about 1 foot / 300mm in length and again position it around the thread and lift up onto the top of the hookshank to secure it. Wrap the floss down to the tag and back up again moving the floss from side to side to try and keep it flattened. Secure the floss a little way further on the hookshank than where we started and trim waste.
Wrap the floss down to where the orange floss was started and back up again moving the floss from side to side to try and keep it flattened, continue doing this until you have a smooth and uniform body. Stop around 1/4 hookshank length from the eye making sure there is no "step" at the next tie in point. Make sure enough space for the under / over wing, hackle and head to be tied in.
Catch the squirrel in on top of the hookshank with a couple of thread wraps. Letting the bobbin hang freely, manipulate the squirrel so that it spreads evenly around the hookshank so you have 360 degree even coverage. (If you find this too difficult, one bunch of squirrel on the top of the hookshank and one bunch of squirrel tied onto the underside of the hookshank will be fine).
Take a golden pheasant hackle and strip away the middle section by snipping it with scissors to leave a gap in the centre of the feather. Once tied in the two sections will come together. Catch in the feather and secure to the hookshank, the feather should just be slightly shorter than the squirrel tips.
Take a cock saddle hackle, holding the tip run your thumb and forefinger down the hackle to force the hackle fibres to sit 90 degrees from the stem. Catch in the hackle by the tip a few wraps to the rear and then one in front of the tip will suffice. Trim the tip.
Making sure not to trap any of the cock hackle fibres, wind the hackle around the hookshank, each turn should be in front of the previous, brushing the fibres back as you wind so as not to trap them. On the final wind secure the stem with two wraps of thread and pull it forward at 90 degrees, secure again with thread. Trim the waste hackle.
