How to Make A Boned Lacing/Modesty Panel

A lacing panel (also called a modesty panel) is a lightly boned panel that fits underneath corset lacing to provide a fully finished look without skin or undergarments showing down the length of the corset. It is usually a separate piece, but is sometimes sewn to one side of the corset or suspended in the lacing to prevent it from becoming lost. The boning is needed to prevent the panel from collapsing while the corset is tightened, but for the most part it is a low-stress item, so I usually make them with a core of cotton duck. If the corset is not made with a separate cover layer, then I use matching coutil.
