You can set up a warm place to sleep, even if you don't have a blanket,
with 4 cardboard boxes.
●Set up the cardboard material as shown above, to create a cardboard house/box large enough for a person to sleep in.
1.Prepare 4 cardboard boxes.
2.Open up each box, and spread in a rectangle shape.
3.Use two boxes and bend to create a コ shape. Let edges overlap.
(Make a square shape large enough for a person to fit inside *Bend the ceiling and flooring slightly.
4.Use the remainder two cardboard boxes--one for the floor, and one as a roof.
5.Enter inside face up. If you close the ceiling, the air stays out, and you have completed creating a warm cardboard room.
