Sialkot is the city of sports goods. Cricket Balls are also being made in this city. Cricket balls are made from a core of cork, which is layered with tightly wound string, and covered by a leather case with a slightly raised sewn seam.
In a top quality ball suitable for the highest levels of competition, the covering is constructed of four pieces of leather shaped similar to the peel of a quartered orange, but one hemisphere is rotated by 90 degrees with respect to the other. The “equator” of the ball is stitched with string to form the ball’s prominent seam, with a total of six rows of stitches. The remaining two joins between the leather pieces are stitched internally.
