I'm installing crown molding for the first time. I have a square room that is a 12 x 12. I know that I need make all inside cuts on the crown molding. I have seven 8ft crown molding lengths. How do I measure the crown? Do I measure from the top angle of the crown that sits against the ceiling. I want to make sure I measure correctly so I get a good tight fit in each corner with the inside cuts. Thanks for any help. Regards.
 
I agree. Too many pieces distracts from the beauty of crown molding.
 
Coping is a must on inside corners. But those 8' lengths are going to be a pain. Do not butt join them in the middle; use an mitered joint at least 30º, then measure the length of the other piece from that. 12' lengths would be best.
 
I use an adhesive caulk and a pin nailer; no recoil from a pin nailer.
 
Caulking will hide massive mistakes, provided you are not using natural, non-painted wood. If that's the case, ya gotta be pretty spot on.

I also have scrap pieces for left and right, inside and outside corners. Sure helps making sure you are cutting at the right angle.
 
One key is to make sure your crown is in the saw at the same angle it will be placed on the wall. If it slips down your cuts will never match. Coping the inside corners is much better than trying to do a compound 45. That said, really complicated profiles can be a challenge to cope and to get to fit.
