    It should probably be noted somewhere that this is more "papercraft" than "origami", and the thing you download is just the net of the solid, not instructions to make what's in the picture.

    Also saddened by the lack of Catalan solids

      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.

        Ah, I didn't see those

          You didn't scroll past the first section before commenting?

            I looked at the page, and decided I wanted to see how to origami some of the archimedian solids, which are lower down the page. I don't find platonic solids as interesting so I didn't click on them. I saw they existed but you can't see that they have folding instructions unless you click on them

            Less than a half dozen of the things on that page have a set of actual origami instructions available. I can completely see missing the few out of all the others because they're the less interesting items on the page.

        Maybe it is a work-in-progress and they just didn’t get around to doing all of them (it’s probably a lot of work). Most of the more complex/compound ones don’t have instructions or nets at all. The paper models are still very beautiful.

        The instructions seem rather sparse, like the Archimedean solids only have folding nets, and not the folding instructions that produce the cool looking pictures with the holes in the faces.

        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.

          It's definitely disappointing and feels like a lazy site to not have much more than "look at these neat origami representations of these shapes.

          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.
