I used to use the small rock wool cubes instead of peat pots. I also used to use a plastic dome, then I discovered a product called Wilt Pruf, it will keep the moisture in while rooting is taking place. Another little trick is, after you've taken the cutting with scissors, cut the stem with a very sharp razor blade, at a 45 degree angle. Then take the blade, and very lightly scrape one side of the stem starting about a half inch from the bottom. You only want to remove the outer hard portion of the stem. This seems to promote faster rooting. Single sided utility razor blades or regular utility knife blades work well. You always want to disinfect the blade by wiping it with 91% isopropyl alcohol. This also removes the oily residue that coats utility knife blades.
