Wood joinery is the backbone of quality woodworking—literally. The strength, stability, and style of a finished piece often come down to how the parts are connected. Whether you're building furniture, home décor, or custom cabinetry, knowing which joinery technique to use (and when) is essential for both beginners and seasoned woodworkers.
