Work on Speed
A great putting drill for working on feel is to simply putt to the edge of the green, not to a hole. This will take away the worry of actually making the putt and turn your focus to rolling the ball with the correct speed.
Putting Mechanics
When you want to work on a putting drill for mechanics, focus on returning the clubface to square at impact. Putt some three footers. If you are not making them consistently, check to see if you are keeping the blade square throughout the stroke and especially at impact..
Pre-Shot Routine
Finally, putt each stroke on the practice green like you would on the golf course. I like to putt with one ball from various positions and never hit the same putt twice. Pretend you are on the course and have to make a putt to win the match. Go through your pre-shot routine for each putt while working on alignment, speed, and making the putt.
