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?

I know this doesn't help you, but...

During my instrument instruction, my CFII was tired of me landing to
the left of centerline on a 150' wide runway. He took me to TEWMAC,
which was (iifc) 26' wide. When I landed on the runway he said "see!,
I knew you could land on the centerline." I replied that I can when
it matters. I still land left of centerline on wide runways.
