First go at this sort of thing

How
I tie it, not how
to tie it !
Dressing
Hook : 12-16 Dry Fly (#14 Partidge SUD here)
Thread: Red ( Danville's Flymaster here)
Body: Rabbit underfur, tip just tying thread ( I like the "tip" to occupy about a third of the body)
Tail : Rusty blue dun cock*
Hackle : Rusty blue dun cock**
* I took the dressing from John Roberts' Guide to River Trout Flies. The cape I've used is a Metz Rusty Dun, which is getting a bit bald now, and the pickings are slim, so I'm not sure how well it fits. Roberts suggests mixing a red game cock with a blue dun, as an alternative. I've always used the same neck - if the pedigree is wrong, the fish don't seem to care
** I'm sure I've seen (online) Hans of this parish putting a hackle on using something like the method below.
1. Wind on a base of tying thread. I come back up a few wraps in advance of tying in the tail
2. tie in the tail
3. I usually just splay the tail fibres with my thumbnail, then take a thread wrap underneath
4. wind the thread up to within about an eye width of the eye.( I remove the tail butts just before - not shown - forgot all about it and carried on tying

) Mount the hackle.Dull side forward (on winding) for me. I just carry the stalk back quite a way to form a smooth underbody
5. dub a robe of rabbit underfur for the body
6. rather than stop where the hackle will be secured , I just carry on and form a bed of rabbit fur for the hackle to sit on. I just find it easier to control the hackle this way - especially if the stalk is a bit fat and unruly
7. Leave the thread hanging where you wish to tie off the hackle
8. wind the hackle back to the hanging thread

9. secure the hackle with no more than a couple of threadwraps. Wind the thread through the hackle. Deliberately.
10. Whip finish.
