Instruction:
Place a chalk line on a straight five-foot putt to practice
on the putting green. Align your body parallel to the line.
The putterface at address will be perpendicular to the line.
With a ball on the line, stroke the putt keeping the putter
moving back and through over the line. If all is performed mechanically
correct, the ball will roll down the line and into the cup.
Repetition will groove your stroke. The more you do it, the
more you gain confidence that the ball starts and stays rolling
down the intended line.
Note:
A chalk line or carpenter's line can be purchased inexpensively
at any local hardware department. The line is not permanent
and will not harm the green. It washes away with morning dew,
rain or sprinkler water.
