This ball can be made of ordinary office paper. In this case it will be more lenient. It’s better to take paper as for greeting card.
Cut out 20 similar circles (I have a diameter of about 6.3 cm – mostly I encircle a cup). Insert into each circle an equilateral triangle.
Now press all the lines under the rules with the not-writing rod and bend circles.
The entire ball is composed of three parts: 2 “caps” with 5 circles and the middle made of 10 circles.
Glue 5 circles together and get a “cap.” Do this twice. Stretch immediately the string or the thread with a knot on the end into one of the pieces to make the ball hanging.
Glue together 10 circles in this way.
Close the bonded tape to the ring and get the middle part of the ball.
Now glue the middle part with the top part and in the same manner with the bottom part.
