1, prepare a rectangular gold paper, face down, and then fold the short side in half to ensure that the width is one-eighth of the length of the square side.

2. Turn the gold paper upside down, then continue to fold the edge folded for the first time into the same width as the first time, and then let the gold paper face down and continue to fold.

3. Fold the unfolded side up and the golden side down, and press it under the golden paper. Fold the just folded part in half, so that the two corners are folded up in turn.

4. Press the top folded part of the other side on it, then let the two corners fold inward, and finally pull outward, and it is ready.
