For places where two pieces of mesh meet at the cross-bars of the lid frame, bend a piece of steel wire into a "U" shape.

Poke each end of the wire through a hole in one of the mesh pieces, with the bottom of the "U" wrapping around the outside of the cross-bar.

Twist the loose ends of the wire together using pliers.

Use wire cutters to remove the excess wire.

Bend the remaining twisted wire down so that it is not poking straight out.
