How to Build a Built-up Cornice

Order of installation: (1) Plywood cleats, (2) Plywood L-blocking, (3) Soffit, (4) Fascia, (5) Frieze, (6) Bed, (7) Ceiling frieze, (8) Crown
Some crown profiles have fine details that would be lost if scribed.
A better example has plenty of surface that won’t show the scribe.

Although the combinations are nearly infinite, most complex cornice designs share common parts. Components can
be added or subtracted, depending on the scale and size desired. In this particular design, I added backing trim on the ceiling that mirrors the frieze below and gives the crown a place to land. The numbers on each part indicate the order of installation.

Keep scribes in mind when choosing crown molding

If a particular design calls for the crown to meet the ceiling, I pick a molding profile that has a meaty top edge. The extra material gives me something to scribe to an uneven ceiling.

Some crown profiles have fine details that would be lost if scribed.   A better example has plenty of surface that won’t show the scribe.
