Drywall Annoyance

[Benjamin Mueller]

So part of my business plan was to buy simple houses. I one floor, no basement smallish houses 700 to 1100 square feet. These are generally 2 bedroom. So this has led me to 5l6 great houses albeit they are all exactly or very close to the same exact layout. They were all built between 1950 and 1960ish.  One little problem I keep encountering is the drywall when I have to put a patch piece of drywall in the original drywall is less the a 1/2 inch but more than the 3/8. So do I just use 3/8 and add some drywall patch a couple times til it's the same width or is there any easier way I haven't  come to realize yet? Generally it is only a small door hole from door lock or something as a plant holder screw etc. Anyone else have this problem and/or annoyance?

@Benjamin Mueller  Use a 'blow-out' patch if the hole is between framing.  

Say you have a 4" square hole:

Cut a 7" square of drywall and mark a 4" square on the backside (1.5" in from each side).

Score along the lines of that 4" square with a knife, going to the edge, being careful to not cut all the way through the front face. 

Snap the off-cuts and peel them away, leaving the front-face paper intact. 

Now you have a 4" square patch with self-contained 'wings'. 

Mud around the opening and insert the patch, wiping the mud from the wings like you would for drywall tape. 

When dry, feather it all out with subsequent coats.
