After seeing some photos of these wonderful book arches,
I’ve been trying to figure out where in my library I could get away with it.
I’ve saved quite a few discards for this and other potential book art.
I wonder how many I would need and how much size and shape would matter.
I’m also trying to figure out how to sell the senior high math teacher
on the idea of one of his classes constructing it for me!
And there is more technical information here.
