Pargeting (or sometimes pargetting) is a decorative plastering applied to building walls.
Pargeting derives from the word 'parget', a Middle English term that is probably derived from the Old French 'pargeter' / 'parjeter', to throw about, or 'porgeter', to roughcast a wall. (Source: Webster.) However, the term is more usually applied only to the decoration in relief of the plastering between the studwork on the outside of half-timber houses, or sometimes covering the whole wall. The devices were stamped on the wet plaster. This seems generally to have been done by sticking a number of pins in a board in certain lines or curves, and then pressing on the wet plaster in various directions, so as to form geometrical figures. Sometimes these devices are in relief, and in the time of Elizabeth I of England represent figures, birds and foliages. Fine examples can be seen at Ipswich, Maidstone, Newark-on-Trent.
