I don't know Richard, sounds like just you and me. So feel free to edit this if you feel it's not of general interest.
However, this handling of "All the Nonconformists" amuses me quite a bit:
The cards are as specified by Mr. Skinner, and, I assume, Mr. Gardner. (for this description, assume the Red suits have red backs, the black suits have blue backs)
Show the four cards face up. Have one named and maneuver it to third from the face, with its color mate fourth.
Flip over the packet, Elmsley count, injogging the last card about the width of a boarder. Perform a very slight buckle of the bottom card, allowing you to remove a double from the middle as apparently an off-color single. Turn the double face up as you remove it, leaving it face up on top of the packet. It will be the named card.
Turn down the double, deal off the single top card, and using that slight buckle, insert it second from the bottom.
Mention that the spectator might just as well have chosen the other black (or red) card. Repeat the count, double lift, and replacement second from bottom sequence.
(Relax, the hard part is over)
Elmsley count, then honestly remove the second card, turning it face up as before. Insert second from bottom.
Elmsley count, turn up the second card, then turn over and put on bottom.
Count hand-to-hand, simulating an elmsley, showing 2 reds and 2 blues.
Elmsley count, last card to bottom, showing three and one. Insert the last remaining odd-back second from bottom.
DM count, followed by a Rhumba, showing all backs the color of the formerly "odd" card.
Pick up the packet, and do Skinner's lift sequence, showing all backs now the other color.
Pause, accept applause, put the cards away. No one asks to see them.
