I don't really buy the leftover fabric argument, but I could see cloth being used specifically for that purpose, or even scarves/mufflers/whatever you want to call them being woven specifically to size. And if they were knitted, I'd expect them to be frameknit, rather than handknit. I dunno. I wish I knew enough to say either way.

God. Who knows, but YEAH, "talk to my boot" pretty much covers it. XD

Ha! That's basically my answer to everything that might involve someone staying healthy and safe. Need glasses to see? Wear the modern ones! Anyone doesn't like it, the boot.
