A method of assembling an adjustable continuous filament assembly whereby a single length of filament is spliced to form a nonadjustable portion and a single free segment. The single free segment is introduced into the inner core of the nonadjustable portion at a first position. The single free segment is passed through at least a portion of the inner core of the nonadjustable portion. The single free segment is withdrawn from the nonadjustable portion at a second position, thereby forming an adjustable portion secured to the nonadjustable portion and adjustable by the single free segment.
