We recently had crown molding installed in a couple of rooms. I can do alot of things involving carpentry, but crown molding is beyond me. I've installed chair rail, shoe mold, and base board but crown molding I don't get. It would seem to be straight forward but there's much more to it than meets the eye. You have to think inside out and it's difficult to visualize the inside or outside corners when you're out making cuts with the miter saw.
We had a friend who lives across the circle install it. He's been a finish carpenter all his life. He said that when someone tells him they're going to install crown themselves, he always replies, "Can I watch?"
