To hang pictures on drywall, gather essential accessories like wire, hooks, and strips. First, locate studs, measure and mark placement, then drill pilot holes and install nails/screws. Use anchors if needed. Wear safety glasses, use a ladder, and avoid wires. Consider framing styles and wall types. For paintings, use D-rings and wire; for photos, use adhesive strips; and for heavy mirrors, use sturdy hooks and anchors. By following these techniques, you can safely and securely hang your pictures, adding beauty and personality to your space.
