What's something about circular machine knitting you've always wondered but have never asked?

I think I told you, but when I make a piece and because of the type or the wool brand I can't finish, I stop the project and do something else with what is knitted. This is the case of this headband which was supposed to be a hot water bottle cover. My Addi didn't like Bernat wool she kept dropping stitches.

First set completed on Caydo

Even if I do say so myself 😛

I’m working on tube number 10 and 11 today. Possibly number 12. I will connect them together before adding them to what’s already put together. But here’s how much I’ve done. right now. I'd have more done than this, except I messed up and was attaching tubes 7-9 to edge of tube #1. Ugh... I was 3/4 done attaching it when I realized I had totally messed up! lol So, I set it aside last night after I took it apart, then this morning I attached to tube #6 like I was supposed to. lol Oh well...
