This art form was passed down from generation to generation with nothing in writing. Due to all information being passed on orally, only the simplest designs were passed on. Around the year1797 the first written instructions appeared. The publication they were in was called the Senbazuru Orikata (Thousand Crane Folding). If visiting an arts and crafts store and learning they do not carry origami supplies, it's likely a salesperson can point the individual in the right direction. Information about origami can probably be obtained from a library. Since this activity is used by many people in society, the library will certainly carry some literature about it. In different parts of the world there are origami competitions where people showcase their work. Origami is an interesting art. It's difficult to visualize this concept. You really need to see pictures and diagrams to help you understand how this idea is applied. There are many books published about origami. Origami is great on rainy days and snow days. Once starting a project, it's difficult to stop until the desired result is achieved. It may take several attempts but eventually the results will be top-notch. Origami has grown in popularity as a teaching tool. Educators and teachers are using origami in the classroom. If you don't open the book before making the second fold you end up with the handkerchief fold which gives you a small square with four layers of paper one on top of the other. The Cupboard - using a square piece of paper make the book fold then open the paper and take each outside edge and fold it to the center line. Scientists and artists have studied these geometric aspects as well as origamists and mathematicians. Mathematicians throughout time have developed ways to use geometry to define origami; they have designed highly sophisticated models using fundamental theorems. They have studied and found amazing similarities between tessellations and origami (tessellations is the name for a figure comprised of a shape that is repeated over and over again with no gaps or overlap when fitted to a flat surface).
