Most notably, V'Ann is responsible for bringing origami into acceptance in the mainstream art world. V'Ann was a tireless contributor to the world of origami and the driving force behind the PCOC conventions. Wendy is honored to teach this wonderful display created by one of the PCOC (Pacific Coast OrigamiUSA Convention) founders, V'Ann Cornelius. With that purpose in mind, Wendy will teach a plinth with the World Origami Days 2021 logo on it so you can display what you are learning and share on social media. Wendy will also teach Laura’s favorite crown, the Canoe Base Module Crown.ĭescription: Folders love to share what they are folding during World Origami Days. Laura was well known for her wonderful origami crowns taught every year at our Annual Convention. Laura Kruskal, Lillian’s daughter-in-law, was also an active participant in establishing the origami community in the United States beginning in the late 1950s. In honor of Lillian’s birthday, Wendy Zeichner (current President of OrigamiUSA) will teach the King David’s crown designed by Laura Kruskal and named after Lillian’s grandson. She famously held folding events in her apartment in NYC, and there are still those among us who attended those events. A dynamic woman, she was delighted in the magic to be found in a piece of paper and wanted to share it with the world. She was also one of the founders of the British Origami Society and OrigamiUSA. October 24 is the birthday of Lillian Oppenheimer (1898-1992), who founded the first origami group in America. Why has it so strongly caught the fancy of the American people? The causes are no doubt varied and complex, but if I were asked to name the single, most effective cause, I would answer unhesitatingly: Lillian Oppenheimer.” About this woman, Martin Gardner wrote: “Thousands of people, of all ages and walks of life, have discovered the pleasures of this fascinating, gentle art. Instead of using origami to explore new ideas in mathematics, some researchers have used mathematical frameworks to explore new ideas in origami.To kick off World Origami Days we are celebrating the birthday of a woman who played a huge role in bringing origami to the West. Or perhaps your questions will lead you in the opposite direction. Then, for a truly mind-bending journey, you might land on the concept of higher-dimensional symmetric shapes. These 3D shapes have a lot of symmetry, though not as much as the Platonic solids. Questions about larger models will lead you to the Archimedean solids and the Johnson solids. Questions about colouring will lead you to the mathematics of graphs and networks (and big questions that remained unsolved for many centuries). One seemingly innocent question can easily lead to a mathematical rabbit hole. Once you’ve mastered the basic structure of each 3D shape, you may find yourself (as others have done) pondering deeper mathematical questions.Ĭan you arrange the sonobe units so two units of the same colour never touch, if you only have three colours?Īre larger symmetric shapes possible? (Answer: yes!)Īre there relationships between the different 3D shapes? (For example, the icosahedron is basically built of triangles, but can you spot the pentagons lurking within? Or the triangles in the dodecahedron?) Julia Collins, Author provided Into the mathematical rabbit hole Sonobe units can be put together to build wondrous shapes. They require no mathematical background but will take you in some fascinating mathematical directions. My website Maths Craft Australia contains a range of modular origami patterns, as well as patterns for other crafts such as crochet, knitting and stitching. So, for a little effort you are rewarded with a vast number of models to explore. Many modular origami patterns, although they may use different units, have a similar method of combining units into a bigger creation. The building blocks, called units, are typically straightforward to fold the mathematical skill comes in assembling the larger structure and discovering the patterns within them. That’s where you use several pieces of folded paper as “building blocks” to create a larger, often symmetrical structure. Julia Collins The ‘building blocks’ of origami modelsĪs a geometer (mathematician who studies geometry), my favourite technique is modular origami. Once you’ve mastered the basic structure of a 3D shape, you may find yourself pondering deeper mathematical questions.
