So just... get a bit of paper towel, put a leaf with some white in it, put it someplace warm but dark, and wait for 3 weeks?
The dry thing is odd, that explains why I had more luck with my Yucca Do 1713 "pullings" that were accidentally thrown onto the plastic parts of my pots then the ones put on the pots itself. Crazy.

When learning something new, it's usually a good idea to learn one good approach, just to avoid confusion. Once mastered, then trying different ways becomes appropriate. Go do it the way Plantae777 suggests.
Having said that, awhile back, I was taught the Joseph Clemens method, which was putting slightly damp soil media in a baggie, with ;eaves sprinkled on top. Seal it and forget about it for a few weeks. By then there should be sprouts. That works.
Then another hobbyist (Capslock) suggested putting leaves on top of the media of the parent plant, uncovered. That works.
People also say to use "winter leaves" as opposed to "growth mode" leaves. I take cuttings any time of year, in both states of growth, and find no real difference, other than winter leaves are easier to work with.
Nearly everything I have, or at least been shipping out, has been from a leaf cutting. Below is a picture of "the farm", from this summer.
Huh. Just had a pull bring with it about 3 1/4" long roots. Anything different I should do with a pre-rooted leaf pull? I put it in the a different pot with the same soil, gently watered it, and put it close to it's papa. I also have another one right next to it, sitting on top of the media, and a third in a dry paper towel, inside a ziplock bag, on the bottom of my plant shelf.
Can you tell I'd really like to get the silly thing cloned?
