Use this quick drill to fix your face angle on short putts
Holing short putts is all about face aim, and ensuring the blade is square to your target line at impact. To train this, narrow your target.
Set up three balls, each on a high tee peg. From a distance of no more than two feet, try to knock each one off in turn by rolling your ball in to the tee peg.
Only a blade square to your target line can achieve it. See how many you can do in a row... then, after missing, keep trying to beat your best score.
