when was the first sewing machine invented
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. Saint's machine, which was designed to sew leather and canvas, mainly on boots, used only a single thread and formed a chain stitch.
