The drywall goes up like normal, The stippling is done by putting your normal drywall mud on a trowel (although a tiling one works better). You put more on the trowel, make it level with the ceiling, and push it lightly against the ceiling. Some will stick, some will come off. you can then level it off with a clean trowel (just dump the mud off) and just push it up so it's even with the existing ceiling. It's somewhat difficult though and requires some practice...
