It was over 1500 years later in 1790, that the first workable sewing machine was invented and patented by the British inventor Thomas Saint. Earlier, in 1755, Karl Weisenthal, a German inventor, devised the first sewing machine needle, but did not produce a complete machine.
For thousands of years, all sewing was done by hand. The invention of the sewing machine in the 19th century and the rise of computerization in the later 20th century led to mass production and export of sewn objects, but hand sewing is still practised around the world.
