Step 1: We fold the square colored paper into a cross crease, as shown in the above picture.

Step 2: Fold both sides of the square towards the center line, as shown in the above picture.

Step 3: We start from the position where the upper origami is about 2cm away from the transverse midline, and directly connect it with the lower origami into a straight line, and then fold the middle origami edge along this crease valley, as shown in the above picture.

Step 4: Take this as the starting point, connect the two right angles of the upper part with a straight line, and fold the same valley into a crease, as shown in the above picture.

Step 5: Fold the whole origami into 16 or 32 equal parts like a folding fan, as shown in the above figure.

Step 6: Tighten the middle and put the rolled butterfly antenna in the middle, as shown in the above picture. Fix the middle with sewing thread, trim the wings a little, and a beautiful folded butterfly will come out. The butterfly in the above picture is divided into 16 equal parts, and the two butterflies in the first picture are divided into 32 equal parts. You can fold it according to your own preferences.
