Re: FOTW question????
Joe pretty much nailed the technique. Leisenring kept cards of premade bodies with different colored tying silks and different dubbing materials so he could make a fly with the perfect body color quickly and easily. (The cards were cardboard with a slot on each side to keep the body from untwisting.
If you can find a copy of The Art of Tying the Wet Fly and Fishing the Flymph by James Leisenring and Pete Hidy, it has all the information on the Leisenring dubbing method and a ton of information on tying wet flies and fishing them effectively.
