I would say the answer is two fold:
First, make sure you are able to set up properly to the club. This is done by using either video or a mirror to check your alignments.
Once you have done that, you want to then make sure the putter is lined up to the target. Nothing comes close to setting down the ball with a big line on it! Make sure the line on the ball is lined up and then take care to set the putter up to that line. You will now have a perfect set-up.
