I received a PM on how I mount a wing in hand. I did a poor job of explaining in written word (I honestly thought I could describe it off the top of my head but realized I skipped some steps when I actually had a fly in hand to mount the wing).
I employed my wife to shoot some stills of the wing mounting steps, hope this helps a little.
1. After marrying wing and lining up your fibers, measure where your tie-in point should be.
2. Place wing on top of tie-in point maintaining a firm enough grip to keep the wing fibers from sliding out of alignment.
3. Transfer your grip on the wing tie in point from the right hand to the left hand being careful not to let the wing alignment slip. (note the imprint on my right finger from when I measured out my wing tie-in on the hook)
4. Firm grip on the wing and one loop over the tie-in point.
5. Tighten loop slowly with even pressure compressing the fibers like an accordion
6. Follow that first loop with a few tighter wraps and a half-hitch (as shown in this blurry image)
7. Here's a shot after I finish the half hitch and a wing preening.
I am no SBS master like Speyducer or Marty, so this might not be of much help. A lot of stuff that I do, I don't even realize what I'm doing.
It would be great if some of the other fellows can pipe in on some of their tricks and tips.

BTW, the fly is Kelson's Purple Emperor (I had been wanting to tie it for a long time and chukarhun99 sent one for FFC and that inspiration pushed me over the brink to whip one up)
