This concept was discovered or invented hundreds of years ago in China and Japan. Although it's unknown exactly where origami was first used, this activity was and continues to be an important part of the Japanese culture. An activity that involves folding a piece of paper has been for generations used both as a pastime and as a challenge. Since this activity is used by many people in society, the library will certainly carry some literature about it. Many articles that are written about origami have references provided that will lead to even more details about the activity. Magazines are a great source or information about origami. There are many craft magazine publications, some printed on a weekly, monthly, bi-monthly, etc. They need to be capable of forecasting the outcome of each step of the origami process. If a mistake is made or a step is skipped, it is quite helpful if the person can figure out where they went wrong. Again patience is needed since an origami project or particular portions of the project may need to be repeated several times. There are several established bases such as the bird, the kite, the windmill and the water-bomb to name a few. Modern origami relies heavily on these existing bases alone and in combination when designing new figures. As an example the kite base is used to make quite a few of the different zoo animals. The more practice a person gets doing origami projects, reading diagrams and understanding instructions, the better equipped they are to take on more advanced origami projects. When individuals become really involved in the art of origami they attempt tougher projects that require several sections. Skilled origamists will take on projects such as elaborate ships, buildings, people and objects involving concentration and logical thinking.
