Lace was originally a heavy texture more like embroidery and of two kinds, Lacis or "darned netting" and Cutwork. Laces, often worked in gold threads and coloured silks was also called " spiderwork." Lace is purely an English word, derived from the Anglo-Norman lacier, to lace, bind, tie or fasten, etc. The word appears to have been first used in 1519. It is a fabric of open mesh or net formed by crossing and intertwining threads. Lace was originally purely a hand craft, but today it is machine made as well. There are three main classes: - Point lace, pillow lace and machine-made lace. Point Lace - When the term " Point " is applied to a lace fabric it should mean that the lace has been made by the needle with a single line of thread, but it is now given to many machine-made laces. There are numerous laces sold as point laces and each has some feature not possessed by any other, many of these laces are known by the town where they are manufactured. Pillow Lace - These laces are made by intertwining threads on pins fixed in a cushion over a pattern fastened on to the cushion. Many pillow laces are part hand and part machine made such as Honiton, Valenciennes, Irish, etc. Machine-made Laces - There are three principal classes which can be placed (1) warp fabrics; (2) plain nets; (3) Levers' laces. Warp Laces - This is the earliest form of lace produced on a machine which was the invention of the Rev. William Lee in 1589, and was an adaption of the stocking frame. A warp lace is a series of upright threads that twist upon each other to form a fabric. There are no crossing threads. They are made in widths up to 10-in. and are the cheapest laces made. Plain Nets - John Heathcote, the inventor of the bobbin-net machine in 1809, laid the foundation of the machine-made lace trade. These are formed by a diagonal bobbin thread intertwining with the upright warp threads so that when the web is taken off the machine the mesh is honeycomb shaped. Other shapes followed, such as the square mesh. Cotton, silk, mohair and rayon are all used in making plain nets. Standard plain nets are as follows: - Brussels Net - Close mesh, specially selected fine yarns, in widths 36-in. to 80-in. The mesh varies up to 20 holes per inch. Both stiff and soft finish. Mosquito Net - Made in many qualities and closeness of mesh and from 54-in. to 108-in. Cable Net - Made up to 300-in. wide and from coarser yarns than other laces. This fabric is used as the ground fabric for curtains, etc. Bretonne Net - A very fine fabric, close mesh and finer yarns than Brussels, very soft and smooth finish. Point d'esprit - Fabrics with spots at regular distances. The yarns are not as good a quality as Brussels. Finished both soft and stiff. Paris Nets - Very stiff finish, used by the millinery trade for foundation work. Illusion Nets - A star-shaped mesh fabric, very fine yarns, used for veils and evening dress purposes. Silk Mechlins, or Tulles - A net more round than square in mesh and made from fine silk yarns. Malines is a tulle made in Belgium. Chantilly, or Silk Brussels - Similar to Brussels, but made from black dyed silk yarns. Chambray Nets - A finer all silk net than Chantilly. Levers' Lace Fabrics - These are various fancy laces and are produced on the lace machine fitted with a jacquard. Samuel Draper of Nottingham combined the jacquard with the lace machine in 1813. John Levers invented the machine. Varieties of these laces are Cluny laces. Torchons, Maltese lace. All-overs and numerous others.
