Moulding or molding (USA), also known as coving (UK, Australia) is a strip of material with various profiles used to cover transitions between surfaces or for decoration. It is traditionally made from solid milled wood or plaster but may be made from plastic or reformed wood. In classical architecture and sculpture, the moulding is often carved in marble or other stones.

A "sprung" moulding has beveled edges that allow mounting between two non-parallel planes (such as a wall and a ceiling). Other types of moulding are referred to as "plain".

At their simplest, mouldings are a means of applying light and dark shaded stripes to a structural objects without having to change the material or apply pigments. The contrast of dark and light areas gives definition to the object.

Imagine the vertical surface of a wall lit by sunlight at an angle of about 45 degrees above the wall. Adding a small overhanging horizontal moulding to the surface of the wall will introduce a dark horizontal shadow below the moulding, which in consequence is called a fillet moulding. Adding a vertical fillet to a horizontal surface will create a light vertical shadow. Graded shadows are possible by using mouldings in different shapes: the concave cavetto moulding produces a horizontal shadow that is darker at the top and lighter at the bottom; an ovolo (convex) moulding makes a shadow that is lighter at the top and darker at the bottom. Other varieties of concave moulding are the scotia and congé and other convex mouldings the echinus, the torus and the astragal.

Jon Peters (born John H. Peters; June 2, 1945) is an American movie producer.

Peters was born in Van Nuys, California, the son of Helen (née Pagano), a receptionist, and Jack Peters, a cook who owned a Hollywood diner. He is of Cherokee (father) and Italian (mother) descent. His mother's family owned a renowned Rodeo Drive salon in Beverly Hills. Jack Peters suffered a heart attack and died when his son was ten, and Helen's marriage to a construction worker devastated the family.

Peters went into the family hair styling business and was successful on Rodeo Drive in Hollywood where he made many industry connections. Peters first gained national prominence when he began dating superstar singer and actress Barbra Streisand after designing the short wig Barbra wore for the 1974 comedy For Pete's Sake. He then produced Streisand's 1974 Butterfly album, from which two songs, "There Won't Be Trumpets/A Quiet Thing" and "God Bless the Child", were later released on her Just For the Record box set - on the liner notes she stated that 'no one at the record company shared my enthusiasm. They thought the songs didn't belong on a contemporary album like Butterfly'. In 1976 he was given a controversial producing credit on Streisand's remake of A Star Is Born. He worked with Peter Guber for the next ten years. Their hits included The Color Purple, Flashdance, Batman, and Rain Man. He headed Sony Pictures with Guber for two years until Guber fired him. The pair were the subject of the book Hit and Run: How Jon Peters and Peter Guber Took Sony for a Ride in Hollywood by Nancy Griffin and Kim Masters.
