The Secret Life of Sewing Machines, Parts1 and 2
 

You can find these videos on YouTube if you're interested...a very funny look at the history of sewing machines with an awesome demonstration of how an interlocking stitch is formed. Highly recommended!:D

Thanks for posting this. I enjoyed both and found a part 3 as well.

Awesome! I will look for Part 3!

Oh, this really took me back. "The Secret Life of Machines" was my son's favorite show, growing up. Thanks for posting about it.
