>basically you use a scrap bit of wood on the back side to to bridge the gap then screw the patch into it.

Extra credit: chamfer off the edges of the hole with a box knife. When you attach the wooden backing, do a few wraps of painters tape around the ends that will be outside of the hole (I guess you'd say the "overlap" but it's an "underlap" or a "behind-lap", right?) Now the backer is inset a couple mm. When you screw the drywall patch to it, it'll be recessed a tiny bit, much easier to mud over it with no "hump". I don't use tape for small holes, like outlet-box sized, and never get cracks this way.

Haha, 1930's house with failing steel supply pipes and un-grounded outlets. Man, I've gotten good with the drywall patching! For small holes, like 1" - 2", I keep a roll of fiberglass mesh tape around - wad it up with some drywall mud and cram it in the hole; when it gets a bit stiff it makes a good backing to fill the hole up, a lot faster than tiny patches or trying to build up a glob on a ceiling (where gravity likes to F with ya!)
