In happier news, my wife bought the most fascinating machine. It knits yarn into a continuous tube. I think I lost an hour to watching it run this morning.

@jerry For really fancy & flexible tubes, get one of these: https://en.wikipedia.org/wiki/File:Flechtmaschine.ogv

That's how you make shoe laces and candlewicks.

@gunchleoc I am old enough to have done that many times on the playground when I was young. It was really cool and super hard to keep organized as I recall.
