ABSTRACT:
A method for forming a garland chain is disclosed, wherein an original chain formed of either long links or of long and short links is worked to produce a garland chain. The garland chain is formed by sliding one link on another so that two attached links are positioned at one end of a long link, and deforming the long link to constrict the central or medial portion, thereby retaining the two attached links at the same end of the long link. Deformation may be applied in the form of crimping, bending or twisting of the links, or combinations of these methods. The deforming methods can be applied to every long link in a chain, or to selected sequences of long links, to create different garland chain effect.
