1. First prepare a piece of paper with the size of 1: 1, fold it in half, then fold it on the other side, fold it twice, draw two perfect circles on it, and cut it out.

2. Fold the perfect circle in half to make a mark, draw a point in the center, fold it in along the edge of the broken line to the center, and make other circular photos.

3. Glue the double-sided regular circles together, make every five into three groups, glue the edges together to form a cylinder, and then reconnect the glued objects.

Take a rope through the middle, then take a piece of paper and cut it from two fifths, which is called scissors for short. Take a rope and tie a knot at one end.

5. Stick the double-sided adhesive tape on the blank, roll up the rope and stick it, the other end of the rope passes through the middle of the previous gluing group and tie a knot, and connect the edge with the gluing edge with the double-sided adhesive tape.
