I am installing a new cornice that runs the width of the room, 12 ft. 6 in. The problem is the ceiling has a sag in the center, about 1 inch at the center. The house is over 30 years old. How far down the wall would I need to mount the cornice to keep people from noticing the sag in the ceiling. I originally was going to install the cornice at the ceiling when I discovered the sag. I'm afraid if I tried to scribe the cornice to the ceiling it would look obvious as the cornice is only 8 inches high. Thanks in advance for any help or suggestions.

You should correct the sag.
If the drywall is simply bowed down from the ceiling, you may be able to insert screws into the joists to pull it up.You need a jack post to raise it back to level.
If it is not the drywall, but the framing, then get in the attic and do whatever is necessary to fix the joist. You may be able to cut out the sagging section and sister new wood to that, install some cross blocking.
Is your roof sagging as well? Have you had water in the attic? You really need to discover and correct the sagging, before you think about the cornice.

scribing it is an option if you eliminate the dust cap and figure out another way to mount it to the ceiling.. it can be done with many L brackets screwed in the back of your face board with 3/4'' screws flush to the top where it meets the ceiling.. After you set all your L brackets you can lift the board up and mark the location of the holes you will need in your ceiling for toggle bolts..
Or
if this is a fabric covered cornice you can use a large welting at the top and this will help fill in the gaps to the left and right of your bowed ceiling.. Try to avoid using any fabric with straight lines or repetitive graphics since this will make a dip in your ceiling much easier to point out.
You would be surprised how much you notice an inch difference in a ceiling, even when you move a cornice board a foot down.. You get this problem a lot in old homes in chicago and its just something most people are going to have to live with..
