Thank Rick, but no need. In his book Bill recommends various substitutes for materials. I've been thinking that the blue patch from a mallard feather would (in my opinion) produce a good looking wing for this pattern (as it does for the butcher). Or, to more closely match a black crow feather, duck or goose dyed black would be fine.

Oh, and I re-read the pattern after posting (posted the pattern from memory, rather than from the book), and he suggests olive thread for the Pop's Gnat, and it is black thread for the Watson's fancy. The red thread that I recalled was a substitute for the GP herl used to make the rear half of the body. I tied one up using the red thread though, and I think the red head looks quite smart.
