Newspapers, plastic bags, environmental protection bags, rain gear, gauze, discarded mosquito nets, paper cups, small cards, discarded CDs, mineral water bottles, cartons, leaves and other materials.

Use an environmental protection bag, cut a small hole in the middle and sew a crotch, and two legs will come out. Finally, you can make a suspender vest.

Specific practice: can't sew, you can use a staple instead of a sewing needle to sew. Tape it together or find some ropes to connect through the holes. Small cards and the like can also be cut out with some patterns to enrich the overall color.
