There is a new video (that I made) of Donna Poster starting the "Foldy Stuff" process, as well as discussing its origins and showing some samples of what can be made with it. The sewing part has a direct angle on the machine and a reverse angle, so it's easy to see what Donna is up to as she's sewing.
Go here to see the video:

I'll look back here to see if it was helpful for anyone.
