Our latest project, a beautiful coffered ceiling, took FOREVER but now that it is finished I can look back and say it was worth it...maybe. Our friend who came to consult on the matter told us we did the crime now we would have to do the time........ so over 150 man hours later we finished our sentence.
We watched a couple of youtube videos on how to put one in but ultimately went with a design by our project guru...you know who you are and we appreciate all of your help.
If you look in the second picture you can see most of our steps. with the exception of the first which was to lay out a grid using 2x4s mounted to the ceiling. Then used boxes were made and screwed into the grid. A strip of pine was added along the edges and then crown moulding along the top.
A couple of things I would have done differently. Waited to paint the walls and prepainted all everything that was going up there and then just touched up the nail holes.
