String inlay is a decorative technique that can add instant appeal to a chair back, tabletop, jewelry box, or other piece of furniture. And while you could use a router to cut the narrow recess required for this accent, Michael Fortune prefers a shopmade cutter he creates from a card scraper. It allows you to work efficiently but without the risk of mistakes that a power tool can pose. It also puts you in control of the width of the inlay. Here, Fortune shows you how to create the inlay tool and how to choose the right wood, cut the strips for the string inlay, and install it.
