Double-curved molding is a type of architectural ornamentation that is characterized by its two curved lines that meet at a point. The most common type of double-curved molding is known as an OGEE, which is a four-letter word that is often used to describe this type of molding. OGEE molding is typically used to decorate the edges of doorways, windows, and other architectural features. It is also used to create decorative elements such as cornices and pediments.
