No mister necessary. Are they tall or low growing? The tall will start from stem cuttings, they start new roots easily. If it's a large clump you can divide the root ball.
The low growing type start easily from stems. If you look closely at them you can see where the little joints are, everywhere they touch the soil they start sending roots out. I find the quickest way is to find stems that are already showing these air roots. Any good potting mix, or your own garden soil if in the ground, works.
Some will actually grow from leaf pieces. You will have to experiment with which ones will do that. I know that Angelina does that. I will have to make a list when I get back home of which ones start easily from leaves.
Hope I have answered your questions Chelle. Sometimes I am not to good at putting thought in print. : )
