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...
