A water-soluble weight is disclosed for attachment to a fishing line, hook or lure by means of a closed loop of thread or string embedded in and extending from the weight which is preferably of essentially hemispherical shape. The weights are formed by filling appropriately shaped cavities in a mold with a mixture consisting essentially of water, soil (preferably a silt-clay mixture having a USDA texture of silt loam) and 10-30 mesh stone. The mold rests upon a layer of resilient material (e.g., sponge rubber) which in turn is attached to a rigid layer mounted by resilient means upon a base plate. Openings in the resilient layer overlie recesses in the rigid layer, the openings and recesses being aligned with openings in the bottom of each mold cavity to permit insertion, with the aid of a tool having a notched end, of the thread or string through the mixture in the mold cavity into the underlying recess. The mold apparatus is attached to a shaker table and vibrated, both before and after insertion of the string, and a blotter material is placed over the mold, in contact with the upper surface of the mixture, which is then dried and removed from the mold cavities. An additional material, such as a fish-attracting food and/or scent, may be incorporated in the weights prior to drying.
