Some of the platonics have folding instructions not just the papercraft net but yeah I wish some of the more interesting ones had actual instructions for the thing being shown too.
Even for the intersecting tetrahedra where instructions are available, I see that it's basically constructing the edges from 30 pieces of paper and then assembling them together. I wish they have more things that were built from a single square piece of paper.
Building from a single sheet is pretty limiting and beyond a cube build like the classic inflatable lantern you'd likely need glue to hold the folds down I think.
