A ball is provided having a tether fastening device, such as a ring plate, affixed to the surface of the ball by a pair of orthogonally oriented fastening strips. Each of the fastening strips has an opening therein, and the strips are located over the ring plate. A portion of the ring plate extends through the openings, and the fastening strips are bonded to the ball body. The fastening strips are preferably oriented at substantially 90 DEG with respect to each other, and at least one cover is positioned over the ball body and over the fastening strips. At least one cover also has an opening therein positioned with the ring plate extending through the cover opening, and the cover is bonded to the ball body to provide a strong and uniformly resilient tether ball. Other embodiments involve either the use of a pair of intersecting nylon cords which partially encircle the ball body and have tethering loop portions extending through the strip and cover openings or a plug threaded into the ball body and having an integral tethering eyelet in alignment with the opening in the strip and cover openings. In yet another embodiment, the ball body includes an outer jute lining having all but a predetermined portion thereof bonded to the ball body. Spaced apart openings in the unbonded portion of the lining receive an elongated flexible stem having an aperture at each end thereof, with one of the apertured ends passing through the other apertured end adjacent the outer surface of the lining. The ball may be used as a sewer ball, boat bumper, float for fish nets, or in games and athletic events.
