Wind the gold holographic tinsel up the hookshank towards the eye. (Doesn't need to be perfectly level, just make sure no thread colour appears between the tinsel wraps). Tie off with thread and trim waste.
Keeping the hackle taught in your left hand, start to wind the oval gold tinsel up the hookshank, its best to move the tinsel from side to side (left to right) as you wind, this stops quite a few of the palmered hackle fibres from becoming trapped under the tinsel. Once 1/3 way up the hookshank you can let go of the hackle.
This part is optional, but I like to tie in a pair of fluo Yellow Goose biots, one at either side of the head. Traditional patterns use Jungle cock but are expensive and I find Goose Biots make a nice substitute.
To tie in, just cut a goose biot to length, tie in with 2 or 3 wraps of thread at the back of the head and pull the waste biot towards the rear of the hookshank, this will put a kink in the biot. Now cut the waste biot on the kink, this should leave you wil a few mm's of waste and will keep the head neat and uniform. Repeat for the other side.
