Chuck,

Great tip... I have used a variation of this for a few years. An 'oldtimer' taught me this; I wish I could remember his name to give him credit.
1. Use a larger hole saw for the hole...
2. On a scrap piece of sheetrock use the same hole saw from the back but do not cut all the way through leave the face paper on.
3. Scribe the back side from the cut outward.
4."peel" the plaster from the face paper, make sure it is pretty clean, trim the flaps to be about an inch...
5. back butter the flaps with thin compound
6. push the patch into place use a large knife to draw the compound out to flatten the flaps.
7. after it dries a little top off with compound and finish.

You can also modify this for a larger rectangular patch
