I am installing new crown molding in my great room. I have existing kitchen cabinets with crown molding at the top. The new crown molding needs to meet the existing cabinet crown molding. The cabinet crown molding is stained alder, the room crown molding is a bit larger and is MDF that I will paint. I'm just an amateur and don't know how to cut the new molding with the exact profile to mate with the existing molding. Any suggestions on how to do this? Are there any articles or books that explain how this should be done?
