I'm working on patching a 12"x12" hole in my drywall, which I had to open up to fix a tub spout. I've added some wood supports for the patch, and I initially thought I could use mesh tape with mud over the seams. But now I'm not sure if I should mud over both the seams and the patch itself. What's the best way to go about this? I've done smaller patches before, but I've never tackled one this size.

California patch is a total game changer! It's super easy and effective.
For the easiest finish, just skim the whole area like you would with a butt joint. This will give you a consistent look after taping the seams. If you have a 24" skim blade, it makes the job a breeze! Here's a quick video that shows how it's done: [https://www.youtube.com/shorts/GsI3sBQIljA](https://www.youtube.com/shorts/GsI3sBQIljA)
Definitely follow the other suggestions about securing the patch to some studs. You could also do a California patch, which is all the rage right now—lots of YouTube videos on that! If you go for that method, you won't need tape. As for mudding, it's really about how smooth you want it. If the patch looks rough, going for a full skim might be a good call, but for a 12"x12", it usually doesn't require that much.
You might want to consider enlarging that hole to 12"x16" so you can screw it into the studs. Adding some horizontal 2x2 strips at the top and bottom will give you a solid base, too. If it's in a hidden spot like a closet, consider putting in an access panel instead—that'll be a gift for future you!
