Use a saw to cut 2 pieces of 9x4x1/2 inch (22.86x10.16x1.27 cm) plywood. These pieces of wood will act as a brace for your drywall. If you cut a hole in your ceiling and you have a metal runner or ceiling beam, then you won't need to create these wooden braces because you can screw directly into the runner or beams instead.  Alternatively, you could cut back the drywall to the center of each of the closest framing members, which would allow you to skip this step. Put the wooden braces that you made out of plywood into the hole and lay it flat over your ceiling, so there is a two inch (5.08 cm) overlap over your hole. Then, screw in two screws through your existing ceiling and into the beam. The screws should be on the top and bottom of each piece of wood. Repeat the process on the other side of the hole. Cutting your replacement drywall two inches longer and wider will leave one inch (2.54 cm) of slack on each side. This is called a hot patch and only recommended to be done on smaller 2-inch x 2-inch (5 cm x 5 cm) patches. Turn over the drywall square and use a ruler to measure 1 inch (2.54 cm) in from each edge of the drywall. Then, use a straight edge to draw vertical and horizontal lines so that it looks like a 1 inch wide (2.54 cm) frame around the drywall piece. This slack will let you blend your replacement drywall in with your ceiling so that it lies flush. With a utility knife, cut through the back layer of paper and the drywall gypsum until you reach the front layer of the drywall. Use the marks that you made on the back of the drywall as a guide while you cut. Then, use a putty knife to carefully peel back the back layer of paper and drywall gypsum, so that the front side facing paper forms a 1 inch (2.54 cm) frame around your drywall patch.  Make sure not to cut too deeply, or you will cut into the front layer of the drywall. You will use the front layer of paper to help blend in your repairs. Your drywall patch can be held in place with lightweight or all-purpose drywall compound. You can purchase this compound online or at a hardware store. Apply the joint compound with a trowel to the edges of the hole. Then, with the trowel, carefully spread it around so that it's evenly distributed. On an angle, push your replacement piece of drywall into the hole. Then, adjust the drywall so that it lies flush with your ceiling. The beams that you screwed in earlier will act like a backboard for your new drywall. Use a power drill to attach the new drywall patch to the wooden braces that you created earlier. Put screws into each corner of the drywall patch to secure it fully.  For small patches up to 2-inch x 2-inch (5 cm x 5 cm), you don't have to use screws. Instead, you can use drywall paper to fasten your patch. Use the trowel to spread the drywall compound over the surface of your drywall replacement piece. Work the edges of the front facing paper into the ceiling with the compound until there are no visible screws and you can't see the edges of the patch. This will require a few coats of compound. You can check if it's dry by touching the surface of the drywall compound with your hand. You must let it fully dry before you can sand and paint it. Use a fine-grit sandpaper to sand down the surface of the new drywall. Continue to use a hand sander so that the new drywall lays flush with your ceiling and you can't see the edges of the patch. You can also use a drywall sanding sponge that's made specifically for drywall. Paint over the new drywall paint using the same paint that was used for your ceiling. If you don't have the original color, you may need to re-paint your entire ceiling so that the new drywall isn't visible.  Be sure to prime the area before you paint it.
