Does any have any experience installing crown moulding when you have a 90 degree wall meeting a 45 degree slope? I tried to send a picture, but no luck. Anyone out there who can tell me how to send a jpg on this thread? Thanks in advance.
You treat the transition like a normal corner, segmenting your way through. Check out YouTube, there are plenty of videos on doing "vaulted ceiling crown".
You can start by clicking right here
You can also use "Crown Drops" to separate the runs in the corners.
