You’ve heard it before: Replace your cabinet or drawer hardware and you’ll completely change the look of the cabinetry. It’s oft-cited because it’s true. Think of hardware as the style signal: A faceted gold bin-pull sends up a flare that says "sophisticated" and "luxurious," no matter your cabinet style. Using upcycled metal parts as drawer pulls sends an artsy-industrial signal. As you browse for new hardware, limit your search to hardware that is installed using the same screw position as the ones you have (single knobs versus bin-pulls versus wide-set drawer-pulls, for example), unless you’re prepared to use wood filler and paint to touch up any holes. And in the case of cabinets, don’t forget hinges! If they’re visible, match them to the new hardware for a pro finish.
