There will be videos, but there still won't be a ceiling. Once you're past the first 10" or so they'll be no walls or liners of any kind so those first few inches don't bother me. I can't take credit for using foil, but I think my method of reinforcement using the cheapest material there is—cardboard from all the stuff we get delivered—is rather novel.
I'm still building this mountain in my mind to see how I'm going to manage getting all the levels of cardboard framing in place, and, more importantly, how the heck am I going to get the plastered soaked towels to all those levels. I can't reach the far reaches from the platform's edge without actually being on the layout and that means I have to do it in stages, including the framing and the plastering. This will me some obvious joints between fresh plastered towels and those that have set up while I'm putting in more cardboard strips. I'll make it work.
