The term 'curvy molding' refers to a type of decorative trim used in architecture and interior design. The most common type of curvy molding is known as an OGEE, which is a four-letter word that is often used to describe the shape of the molding. An OGEE is a curved line that has two arcs of opposite curvature, with the convex arc typically above the concave arc. This type of molding is often used to add a decorative touch to walls, ceilings, and furniture.
