First, I take a small cutting from the plant and remove all but one or two leaves.
Then, I wet the stem and dip it in some powdered rooting
I plant it in a mixture of sand and peat moss, water it, and cover it with plastic to keep the moisture in.
I don't really know why this appeals to me; other than the obvious fact that I can get free plants. That in itself, though, is hardly worth the trouble because the new plants are so small--you could buy larger plants for just a few dollars. There is a bit of mystery, I suppose, in taking a little cutting and growing an entirely new plant from it. It doesn't seem like it should work, but often enough, it does.
