If I were sending you the cuttings, I would snip a 12-18" whip from the new growth. I'd snip it about 1/2 inch below a leaf node, and remove the bottom 3 sets of leaves. Then I'd wrap some moist tree moss around the bottom 3 inches of stem and seal the moss in a plastic baggie, roll the vine up and toss it in a bubble envelope and send it off by quick mail...
That's what I'd do. :wink:
