Use artistic wire, Beadalon beading stringing wire, and other flexible stringing materials to Weaver unique ring designs. Slip the pegs into the holes that correspond with the size ring that you want to make. These pegs are knurled so that they slip into the holes on the underside of the tool and stay in place with the included Disc. One toll makes rings in sizes 4, 6, 9 and 11 that fit most people. The diameter of the stringing material will adjust the actual ring size- larger materials will make smaller rings.
