I wrote this article about Sewing machines. The history and the mechanics of how it replaces the complex action of stitching that usually a human can provide. While researching for the article, I learned a lot. Things like "Barthelemy Thimonnier," one of the inventors of the machine was almost killed for inventing this machine.
I really think this article tries its best to collate all the information I could gather about this machine. Please have a look and let me know where I could do a better job. If you learn something new, feel free to write me back about it as well.
Thank you, guys!
