People have been unknowingly folding and cutting orbifolds of symmetry groups for hundreds of years, in the form of paper snowflakes and paper dolls. But now that more research has been done on orbifolds, we know of more foldable symmetry groups than ever before. Previously, people have explored how to fold paper into the orbifolds of the Frieze groups and 2D point groups, but in this workshop we'll take our folding skills to the limit with wallpaper and spherical groups. Using large sheets of paper, spherical beach balls, and some sharp craft knives, we'll see if we can make them all!
