History
Charles Fredrick Wiesenthal, a German-born engineer working in England was awarded the first British patent for a mechanical device to aid the art of sewing, in 1755. His invention consisted of a double pointed needle with an eye at one end.

Thomas Saint's chain stitch used on the first ever complete sewing machine design for leather work. An awl preceded the eye pointed needle to make a hole in preparation for the thread.
In 1790, the English inventor Thomas Saint invented the first sewing machine design, but he did not successfully advertise or market his invention.[3] His machine was meant to be used on leather and canvas material. It is likely that Saint had a working model but there is no evidence of one; he was a skilled cabinet maker and his device included many practically functional features: an overhanging arm, a feed mechanism (adequate for short lengths of leather), a vertical needle bar, and a looper.
Sewing machines can make a great variety of plain or patterned stitches. Ignoring strictly decorative aspects, over three dozen distinct stitch formations are formally recognized by the ISO 4915:1991 standard, involving one to seven separate threads to form the stitch.[20]
Plain stitches fall into four general categories: chainstitch, lockstitch, overlock, and coverstitch.
