According to my experience, the production method of fox headdress is to prepare a square piece of cardboard, then fold it into a triangle as shown below and press out the crease. Fold the triangle folded in the last step in half again, press out the crease and unfold it. Fold off the corner at the top of the big triangle. : At the center of the lower end of the crease, fold the right corner in the previous step obliquely upwards, and also complete the folding of the left ear. On the folded fox head, only the fox's eyes and black nose are drawn.
