I'm having an issue with 2 students.

One has a hard time lining up/staying lined up with the center line
(no wind and xwind). I keep telling him "toes forward" and "Have the
center line cut through your body"

Still not grasping it.

The other student, likes to be 10-20 degrees angled left / right of
center line before touching down (ie. side loading)

Any tips?
