First, start by folding in half and making a small crease. then, fold this corner to the crease. now, fold the edge of this triangle to the centre after that, fold the tiny corner up to meet the line. repeat on the other side. fold the other corner to the same crease in step one. bring down the edge as in step 3. turn over. fold the corner down to meet the edge. fold the parallel corner up to met the parallel edge. Repeat on other side. notice the two points , imagine a line between the two and fold to create a square, repeat on the other side. see the middle square, …. fold two diagonal line in it like this. turn back over. open the edges.
