We're going to hit a left to right putt, which is 20ft away to this hole just over here.

The first stage is to get down behind the ball, so that I can look at the ground between the ball and the hole where I'm aiming. I can look at the ground and the way it's lying, and judge how much the ball is actually going to break.

Getting down low gives you a much better idea of the lie of the ground, and how much the ball should move one way or the other. 

Once I have established the line of the putt, what you can do is mark your golf ball. Put a marker behind the ball and get down low again, and aim the writing that is on the golf ball to a point that's on the ground which I've established might be about 3ft left of the hole. Once you've got the writing aiming where you want it to aim, we can remove the marker.

We now have the line of the putt. I've lined the ball up, pointing in the direction that I want the ball to go. I'm now going to have a couple of practice swings before I hit the putt, to give me a feel for how hard I want to hit this particular putt. 

I take my stance just this side of the golf ball, still aiming in the direction that I think the putt is going to break. I'm going to have two or three practice strokes, looking at the hole whilst I'm doing so, just to give me a feel for how hard I want to hit this putt. 

Now I'm ready. I put the putter head aiming where the writing on the ball is aiming and I can take my stance which is parallel to the putter head so everything is now parallel, pointing about 3ft left of the hole. Once I have my stance, I'm going to make sure that my eyes are over the golf ball, and that the ball is just left of centre in my stance. Once I'm in that position I'm now ready to hit the putt.
