Can you build these arches?

These two arches that we propose to build with cushions, are representative of a great variety of existing arches. 

  • The catenary arc is named after it because it follows the shape of a catenary curve that is the one that adopts a chain held by the ends. It must be built with the help of the wooden support (called cintra or cindri) and following the order of the cushions indicated by the colors.  
  • The semicircular arch is shaped like a half-circle, it needs side supports. It takes 4 hands to build it.
