When mouldings are decorated the details ranging above each other should be so distributed as to fall in vertical alignment. This is particularly necessary when the Ovolo enrichment occurs below dentils, or where it is surmounted by Modillions as in the Corinthian cornice.
Panel mouldings cannot legitimately be considered as functional in the foregoing sense, though in wood-work they are directly incidental to the construction. Regarded as frames, their general purpose may be considered as to bind or enclose.
In stone-work it may be at times desirable to introduce panel effects, which may be obtained by boasting out or recessing parts, possible only on a large scale.

Panelling in wood-work is not only legitimate, but structurally necessary, as it is not practical to cover large areas except by some method of building up.
