Abstract: The present disclosure provides a string adjuster for lengthening or shortening jewelry chains, threads, ropes, or other materials with layering capability/adjustments. The string adjuster may take on any decorative shapes to be a clip or a charm. For example, an adjuster for changing a length of a string loop formed by the adjuster may include two or more channels for receiving the string. One of the two or more channels provides a tight fit to the string. The adjuster further includes an anchor disposed in another one of the two or more channels for affixing an end of the string to the adjuster.
