ditto, what twitcher said regarding doing multiple cuttings. In a nursery you should be able to get 6 or 8 cuttings and have a better success rate. I do many of my cuttings in plastic bags also. It sure makes it easy to allow excess condensation out as well as air/gas exchange if you use a bag big enough that you can easily open and close the top.
