   Crease each outer third in half, making four narrow panels and one wide middle panel.

   6. Fold the right outer panel

   Fold the rightmost narrow panel over its neighbour too.

   9. Fold the bottom corners

   Fold both corners diagonally inward, bringing each outside edge to the crosswise floor crease.
