Uneven ceiling ... need to get a level!!

[jimn]

Hi all,
I am planning on putting up an electric curtain track which is 10M long with a 90 deg bend about 1/3rd along.
The curtain will hang directly below the track and does not cover it.
my ceiling is plaster on plaster board over a wooden ceiling over joists ( OK to fix too)

this be my problem
My ceiling to floor measurement varies about 4cm - up at ends and lower in the middle. just like a smiley face,:lol:

My curtains need to hang approximately level or they will look bad at floor level. higher and lower across the span.

I thought of packing out using spacers and a plumb line to get it level to the floor.
and then covering it with a bit of upvc trim shaved down to the track depth off the ceiling.

please anyone got any ideas of a better way or finishing

kind regards

JIM

YES correct solution but use a level not a plumb line.

THANKS stoneyboy... but I think my Floor AND my ceiling are not true! so getting a level on ONE may put me out with OTHER. hence the plumb line idea.. grateful for your input - I feel confident with the upvc finishing edge now - thanks JIM
