Goal: How to cover up nail holes in the wall.
From the hardware store you will need spackling, fine grit sandpaper, a putty knife, and paint. Put a little spackling on the knife and apply it to the hole. Use the straight edge to scrape away any excess from the wall. Allow to harden and sand until smooth. Paint over it with a color that matches your walls.
