My first is at about 8cm unblocked. I would like it to be a bit bigger than I am tall so current estimate is that I’d need about 400 of these to get to the size I want.
that’s a bit overwhelming but absolutely doable. I read 400 pages without thinking about it. This isn’t going to be finished next week.
I think all centers need to be a full or semi solid. Everything else is fair game.
