You can make this very beautiful paper ball with 30 similar modules folded from square papers. Each square should have a 10-cm edge. Fold a criss-cross in a square like a multiplication sign. Then fold a plus sign. All these four folds will be in the same direction. Then fold all the four corners to the centre to make an envelope. Open two opposite flaps to make a hexagon. Then fold the left corner to make a skewed triangle. Fold the diametrically opposite corner to make another skewed triangle. Now fold in half and simultaneously tuck the small triangles inside. It will become a heart shaped and on pinching it will become a STAR. You will need 30 such pieces to make the BALL.
Now take two units. Insert the beak of one into the pocket of the other. If they come out you can also glue them in place. Assembly 5 similar units into a Pentagon shape. Make 5 Triangles around the pentagon. You see the first triangle taking shape. Slowly make 5 Triangle to complete one big unit. 
Keep assembling in a similar manner and slowly a very elegant 30-unit Ball will emerge.
