The present throwable article is a toroidal-shaped ring of tightly-rolled elastic-knit fabric, such as by using knee-high sport socks. The number of layers in the roll may vary, but preferably include 15-30 layers or more of rolled fabric, such that the cross-sectional ring is a solid and relatively tight mass. Size and shape may be varied, but it is contemplated that the size will preferably be kept about equal to or less than a softball such as 3-½ to 4-½ inches outer diameter, and with a weight of about 3-5 ounces. The throwable article is useful for training and/or for live games. It can be tailored in size, shape, weight, and functional characteristics for any game, any age and any environment.
