Use a putty knife, loaded with a spoonful of joint compound or spackle, to fill holes in the wall.

If the holes are larger than these nail holes, please read "How to repair a hole in your wall."

Push spackle or joint compound into the holes by pushing on the the putty knife and dragging it down against the wall.

scrape the wall with the putty knife, removing any extra spackle.

Paint! Unless you have super-smooth finished walls, the choppy texture of the spackle will disappear into the rest of the wall.
