Any home interior contractors on here?

I'm remodeling one of the rooms in the house. It's time to hang the crown molding, but I have a few questions.

First, let me state, I don't have a compound miter saw. This is all being hand cut.

Can I miter and cope only one end of each interior corner molding and butt cut the other end or does each end have to mitered? There's one exterior corner in the room where the wall juts out six inches for the room's door.

You shouldn't miter crown molding, at all because the miters will open has the house moves and settles.

The easy way is to install the two longest opposing pieces with butt cuts. than on the intersecting walls you do a cope.

Jim is spot on with the splice idea. Splicing those two pieces together is the easiest and most accurate way to deal with that, just be sure that the spice you make is at 45ยบ so that if there is some separation over time, it really doesn't show.
