Papercraft is a form of crafting in which paper is used to create three dimensional objects such as models or sculptures. Some people refer to papercraft as pepakura, in an homage to the large Japanese papercrafting community. Papercraft can be large or small, humble or ambitious, and it is incredibly varied. It is also easy to learn, and the Internet has greatly facilitated the exchange of papercraft designs and patterns. In addition, many Internet forums provide useful tips for budding papercrafters who may be struggling with their work.
Unlike origami, papercraft involves cutting up paper or cardboard and gluing it back together, although some folding and bending may be involved. Very basic papercraft is often taught in schools, so that children can bring polygons to life in the form of polyhedra. Simple papercraft does not require extensive math skills, but it can be used to illustrate basic math, or to get people excited about mathematics. More advanced papercraft can call upon impressive math abilities, which is part of the fun for some crafters.
