Polyhedra are beautiful shapes. Origami master John Montroll provides clear instructions for folding these original designs. Each model is folded from a single square adding magic to origami. Here is a collection of 36 origami polyhedra models ranging from simple to complex. The Platonic Solids are shown, along with color-change models, dipyramids, dimpled and sunken models, deltahedra and more. Many of these models use folding sequences that allow them to be folded in fewer steps.
