This would be good for children who are having trouble communicating or getting along with other children. This activity requires patience and so it teaches people how to be patient. Again this would be beneficial for children. Origami involves problem solving and this is a skill that is needed daily by individuals of all ages. For simple projects such as a paper airplane or a crane, normal copy paper (19-24lbs) is sufficient. For people who are learning this art, using normal copy paper would likely be a smart idea since it would be less-expensive than buying fancy origami paper.

Buildings: Fumihiko Maki designed the Kirishima International Concert Hall. This hall was built using the architect's trademark brushed silver surfaces and was located on a secluded mountain site. Thousands of people have made paper airplanes not knowing they were doing an origami project. In order to make a perfect paper airplane, it is essential to use exact folds in the paper. This is what the art of origami is about, making precise folds to create a specific object. In the early days when origami was initially discovered, it was used in Germany by kindergarten students. It helps them develop reading and writing skills, teaches them about sequencing, as well as teaching them to concentrate, be patient, be attentive and use their imagination. Because children tend to change their minds quite often, choosing origami as a hobby is a smart choice since it is relatively inexpensive.
