California Patch

California patch
is a popular, backing-free drywall repair method for small to medium holes (up to about a foot), where you create a paper-backed patch from a spare drywall piece, leaving paper "wings" that get mudded and blended into the wall for a seamless, invisible fix without needing wood supports. Also called a butterfly patch, it's favored for its simplicity and effectiveness in creating smooth, durable repairs by "feathering" the mud over the paper edges into the surrounding wall.
