Hi, Beth. OK, now we understand the problem. Let's fix the wallboard. From the sound of it, it will be easier and better to replace the section of wallboard with the bad surface. Look around for indications of where the drywall was nailed (or screwed) to the studs. Using a straight edge and matte or utility knife, cut the wallboard just next to the heads of the nails so the present nails hold the section you don't want to remove to the stud but you will still have part of the stud available for support and nailing. Also cut across the top and bottom of the section and next to the meeting wall. Now go to the home center and buy a sheet of wallboard the same thickness, joint compound, screws or nails (depending on what tools you have), drywall tape and one wide and one wider joint compound knife. Cut the new drywall to the exact size to fill the hole by scoring the paper on one side with the knife and straightedge, snapping it back from the score so the gypsum breaks, then cutting the paper on the other side. This is really easy. Put the drywall in the hole and put it in with nails or screws so that the fastners just dent the surface of the paper but don't poke thru the paper. Also nail or screw the drywall into the other intermediate studs that were exposed in the process. You should end up with nails or screws about every 6" along all the studs. Apply joint compound to all the edges forcing it into any gaps and then put tape over that. Fold the tape longways to make it fit easier into any inside corners with the old wall or ceiling. Mash the tape into the compound with the knife sliding it along the tape. Then put compound over any nails or screws that you did not already cover. Let the compound dry and apply another coat of compound with the wider knife so you feather out the extra thickness over a wider surface. Let this dry and sand with drywall screen and a sanding block so the new compound feathers into all the surfaces. You may have to apply a third coat depending on how this looks so take a close look at it and see if you would be happy with it if it was a painted wall surface. Then have a cup of coffee while you congratulate yourself on what a great job you did.

Don't forget to seal the new drywall--and the old also--with something like BIN primer sealer before you repaint or repaper. Definately keep the rest of the drywall you bought around somewhere. You might punch a hole somewhere else carrying lumber around or something and now you know how to patch a big hole. And if you ever decide to try faux painting, you have great practice pieces.

Good luck.
