K wrapping headliner around the air vents

[N231SM]

Does anyone have a pic or know where I can find one showing the upholstering of the air vents on a 1980 vintage 231?

 

I am at a standstill on proceeding with local upholsterer because they cannot figure out how to get those vents done.  I talked to Aerocomfort. They said they use "seams" in those areas. ??

In the pic below, does anyone have a headliner wrapped with fabric around theses vents?, . If so, what material was used?  Thanks

 

I have attached a pic of these areas.

Are you talking about your eyeball vents or the speaker fabric?
