The fly in the first post is
mine, and there's a link to Charlie Craven's tutorial in my second post. No
matter which way you tie in the hackle, it's important not to use too many
wraps over the hackle. One extra wrap toward the back of the hook will draw
the hackle down over the hook shank. Having a little thorax helps immensely.
Don't get to caught up in Charlie's details about making the V cut. I just
draw all the barbules down, and snip off what's between my thumb and index
finger. Same thing, but without getting too complicated.
P.S. I just looked at Charlie's tutorial again, and it should be pointed out that the stem is not tied onto the hook.
Cliff's method does use the stem, and works very well if you have the right size hackle. I buy mine in bulk bags, and
Craven's method makes even the biggest hackle work on the smallest hook. Charlie's hackles seem to be swept back
a bit more than I remembered, but even a tiny thorax will solve that.
