Try this........start with a dinner plate size plastic circle,
then a saucer size and ultimately a coaster size round
circle. When you practice, place the circle where you
want the cue ball to wind up. You get to practice using area
shape or as some refer to it, window shape. At the outset,
use the biggest circle. As you get better, reduce the size.
Get the cue ball to land within the circle. It’s a mini version
of Target Pool. You just reposition the circle for the next shot.
If you get good at this, pretty soon you will just substitute a
marker or just a coin. Heck, place a piece of chalk upside down
for the position and the cue ball has to strike the chalk. Make
it into a version like bottle billiards. I use a Pebble Beach golf
ball marker & place it where I want the cue ball to stop for ideal
position for the next OB. How close I come tells me how well I
am playing that particular day & it makes practice a li’l more fun.
