Let me add just a little to Horace's discription as he teaches the same as I teach.

Whne you have the plane lined up coming toward you watch it carefully and try to deturmine if it is coming right toward you in both direction and sink rate. In other words it should be heading straight at you. If the plane is gaining altitude going over your head then reduce power a click or two. If the plane is sinking toward your feet then you need to add power a click or two. This will make you land almost in front of you and is a great technique for spot landings.

Above all, if it looks bad in the beginning then it will be a bad landing so just add power and try again.
