John,

Tom got in today and stopped by this evening so I asked him your question. The hackle is wrapped and then it is divided into two bundles, like you would tie a hackle-winged spinner dry fly, figured eight wrapped to seperate the wings and then you wrap your thread around the base of each wing, like you would on the post of a parachute pattern. This stiffens the wing and keeps it from folding flat back aganist the body of the fly when its being fished.

Hope this helps. Tom said he had images of those patterns if that would help.
