Step 2, continue to fold it twice along the middle line, as shown in the figure below.
Step 3: Then fold the inside into two triangles according to the folding line, and display them as squares after pressing, as shown in the following figure.
Step 4: Continue to fold both sides to the middle along the middle line, left and right in turn, and positive and negative corners in turn, as shown in the following figure.
Step 5. Then unfold the folding in the previous step, and fold the edge inward along the fold line after opening, in the order of positive and negative, as shown in the following figure.
Step 6, then fold the two sides against the middle line and flatten them. The reverse side is also folded in the same way, as shown in the following figure.
Step 7, then close the front and back folding areas, as shown in the figure below.
Step 8: Continue to fold down the paper on both sides, and you can see paper crane's wings, as shown in the figure below.
Step 9, then pull the middle two vertical ones out a little, and fold out the head and tail, as shown in the figure below.
Step 10, and then spread the wings on both sides, so that the paper in the middle is flattened to form a square, and paper crane will be folded here, as shown in the following figure.
