What are some simple and interesting manual activities suitable for college students?

I think simple handwork includes cardboard handwork, small handwork transformed with some waste materials, small handwork without weaving, and handwork made of clay or plasticine is also relatively simple. The simplest handicraft should be a small handicraft made of cardboard. Cardboard is the simplest manual material, and many simple and easy-to-learn small handwork can be made of simple cardboard. Fold a few sheets of paper, cut them open, draw a picture and stick them together, and you can create many small things. It's simple, interesting and amazing. I also like handcraft, and I made some simple and easy-to-learn small handcrafts with cardboard.
