This is classical model, the folding of which involves passing through several origami bases such as the book fold, the cupboard fold and windmill base. Use 2 squares of paper, identical in size. Start with colored side down.
|Valley fold the inner two edges of each small square over, so they lie along their respective square's middle fold-line. Press them flat and unfold them.||Mountain fold the four corners behind as shown, thereby making little triangles on the reverse side. Press the paper flat.||Open out each flap, so that its edges meet in the middle, as shown in the next step.|
