There is another exercise I used to use in the intial stages of aero instruction that you might like to try.
If you set up a wing rock of around 30° left and right, while flying straight and level, and with your feet off the rudder pedals, you can show how the nose of the aircraft wags back and forth in a "U" shape, due to the adverse yaw.
Now do the same wing rock, but with rudder input, and you should be able to nail the nose in the one place, with practice. It is initially like trying to pat your head and rub your stomach at the same time.
It amazes students how much firm rudder is actually required, like around ¾ travel.
