Droopy Headlining in my 1999 GTV V6

[geeman1963]

Hey there

This morning I thought i'd grown about 2 inches as I was rubbing on the headlining in my beloved GTV V6.
But no,  it has come down to meet me!

The area to the RHS of the drivers cranium is drooping,  the rest is immaculate.
It's a fine black mesh cloth,  nothing furry or weird

Any ideas for a quick and easy-ish fix,  or am I off to the motor trimmer?

If it's the latter,  can anybody recommend a good one down near Aspendale Gardens?

Cheers!
