To repair a broken drawer, assess the damage and gather necessary tools and materials. Clean the damaged area and apply wood glue to the broken parts. Use clamps to hold the parts together as the glue dries. If the breakage is severe, reinforce the joint with screws or dowels for added strength. Once the glue dries completely, remove the clamps and sand the repaired area to smooth any rough edges. If needed, apply paint or finish to match the rest of the drawer.
