I thought I should give a little run down in one place as to how I completed my coffered ceiling project just in case you want to try this project.
I then used a 2x4 to set my table saw to cut the strips of MDF for the bottom pieces approx 3.5" wide.
I used this new gadget from Lowe's to help me with the crown moulding, it just keep the crown moulding at the proper angle when you cut it upside down.
So if you have ever longed for a coffered ceiling like I have for years then maybe it is something you can do also. It is not a difficult project but it does take time and patience and have a helper for the initial stud placement is necessary but the rest I was able to manage on my own, I may have had to hold my nail gun in between my knees while I positioned the 8ft pieces of MDF but a girl's gotta do what a girls gotta do.
If you try this project please let me know I would love to see.
