Because of low ceilings, I'm having to do the "faux" coffered ceilings, using 1x4s instead of actual box designs for the coffering. One fellow mentioned that it's not necessary to take the coffering into adjacent hallways. The passage to our hall is not a standard headered doorway, but an open smooth flow of den to hall ceiling. It seems sort of cheesy to end the coffering in the den with a trim piece where the hallway begins. Is there a good way to stop without going down the hall, or is taking it down the hall better? By the way, I'm getting rid of old popcorn ceilings. Thanks.
