There are two ways to practice the short game. First are how-to shots, where you learn how to control trajectory through set up and swing shape. Second are situational shots, where you move around the short game area and practice specific shots.
Create an imaginary line to the target when lining up your shot then aim with your eyes down that line in order to hit your target
Opening and closing the face of the club too much during the backswing and downswing will cause you to hit the ball with the toe of the club
