Origami is the art of paper folding. The name "origami" is Japanese—ori meaning "folding" and kami meaning "paper". Origami began in the 17th century with the creative folding of napkins.
Origami started out as an unusual hobby. Since then it has become much more popular. That's mostly because it is easy to learn. After following a few simple instructions, most people can make a basic animal or a pretty object. Also, you don't need much to make origami. All you need is a piece of paper and your hands.
Most origami folders believe no tools should be used to make origami. They think you should use only your hands. However, a couple of tools can help, especially when making complex shapes. For example, a ruler can be used to make sharp creases. Paper clips can act as extra pairs of fingers. And tweezers can be used to make small folds.
