I only used PVA Glue on each side of the card (before cutting).
You could coat the paper in CA Glue for better rigidity and strength
but I don't know how that would affect cutting out the parts.
I think a PVA Glue coating cuts a lot easier and cleaner.
You could soak the parts in CA Glue
after they have been cut and formed?

I guess its hard to judge the scale from my photos,
so heres a shot that better shows the size of the railings.
I'm not sure about cutting 1mm or thinner Railings,
but you can definitely cut the glue soaked paper pretty fine.
