Once practiced traditionally in East Asia (particularly Japan) for the purpose of religious ceremonies, the skill of folding paper, origami, has become a worldwide art, education tool and stress release. 

The properties of origami for children have a variety of known educational benefits. However, one particular study into the academic benefits to origami found that ‘4 hours of Origami instruction received per week [...] may very well have contributed’ to a rise in mathematical abilities of US university students (Boakes, 2009, p. 73) suggesting that origami is not necessarily just child’s play. Origami can actually improve both your mathematical ability and spatial skills (Boakes, 2009, p. 72). From cute bunny rabbits to adorable cats there are a variety of origami tutorials you could choose from to try out and have fun with. Yet rather than creating decorative items, if you’re a more practical-minded person and want to create something that you can use as well as display, there are plenty of tutorials to help you with this too. This useful tutorial on how to make a mouse corner bookmark can be used to keep note of pages in your university texts. This strong box or desk organiser can help you collate all of your university equipment. A quick hack on how to seal your share bag of crisps in the library can be super helpful if in a rush to get to your next lecture. Or make yourself a portable phone stand so you can change your background study music with ease.
