In the West, tassels were originally a series of windings of thread or string around a suspending string until the desired curvature was attained. Decades later, turned wooden moulds, which were either covered in simple wrappings or much more elaborate coverings called "satinings", were used. This involved an intricate binding of bands of filament silk vertically around the mould by means of an internal "lacing" in the bore of the mould. A tassel is primarily an ornament, and was at first the casual termination of a cord to prevent unraveling with a knot. As time went on, various peoples developed variations on this.
