Use a drywall saw to cut a rectangle in the ceiling that encloses the hole. Measure the dimensions of the rectangle with a tape measure and cut a piece of drywall to fit. Spread drywall joint compound around the perimeter of the rectangle with a 4-inch drywall knife, and lay moistened paper drywall tape on it. Scrape the tape flat, and remove excess mud. Topcoat your patch, no matter what size it is, with at least two coats of mud.
Apply each coat after the one underneath it has dried, and scrape it flat with a wider knife than the one you used to scrape the previous coat. In this way, the edges of the patch will feather into the wall and be invisible. Texture the patch to match the rest of the ceiling.

Prime the texture with drywall primer when it dries and then paint it with the ceiling color. Chris Deziel has a bachelor's degree in physics and a master's degree in humanities.
