1. Prepare rectangular gold and platinum paper.

2. Golden face down, folded in half

3. Fold one side down by about one third.

4. The other side is folded in the same direction and aligned with the broken line of the golden face.

5. The four corners are folded in half with the intersection of gold and white as the axis, and then the non-gold part above is turned down to become a trapezoid.

Open the long side

7. plastic surgery, the ingot is finished

2. How to fold this ingot?

Illustration of ingot folding method: 1. Prepare a square piece of paper, and then face it diagonally so that the corners are aligned with the corners. 2. Fold the square paper in half, then fold the center of the long edge in half, and then align the corners. 3. Open the corner of the second fold, then fold two corners up along the middle crease, and align the edges after folding. 4. Open the two corners folded from the middle respectively. Align the edge with bevel edge 5. Turn the folded paper upside down, and fold the two small hypotenuses at the bottom to the top. The folded edges are perpendicular to the bottom 6. Fold up the two edges of the folded edge along the outermost two creases, and then align the edges. 7. Fold a long corner up along the hem, and then fold the upper corner into the hem. 8. Fold the long corner on the other side as above.

Then flatten the middle edge, arrange the corner ingot and fold it.

3. Several folding methods for stacking three sheets of paper.

The folding method is as follows: 1. First of all, you need to prepare a rectangular gold paper, with the golden side facing down, and then fold a short side, the width of which is one-eighth of the length of the square side; 2. Then turn the golden paper upside down so that the golden side is up, and then continue to fold the edge to the same width as the first folding; 3. Then we turn over the golden paper that has been folded twice and continue to fold the golden side down; 4. Then we fold the unfolded side up and press it under the first folded gold paper; 5. Next, we will fold the two corners of the just folded part upwards in turn; 6. Then we press the top folded part of the other side onto the whole paper; 7. Then we fold the two corners of the just-pressed part inward; 8. Then we pull the two sides of the ingot outward, so that a gold ingot is finished.

Next, just repeat this step and you can stack the desired numbers. Extended data:

Before making origami, it is best to remember the basic folding methods and origami symbols. The following are commonly used folding methods and symbols in origami charts, that is, the Ji Ze-Lan Park Jung Su system used in general origami charts: valley folding: folds are folded into valleys, which are represented by short dashed lines in the chart.

Mountain-shaped fold: the scratches protrude outward in the shape of mountain peaks, which are indicated by alternate long and short dashed lines in the figure. Fold out the crease and open it: fold the crease in the mountain and fold the crease in the valley.

Fold: Fold repeatedly in the same direction. Layer folding: valley folding and mountain folding alternate.

Middle folding: Fold the crease according to the peak line; Thumb inserted at the bottom, index finger placed at the top; Press the index finger down to make it overlap with the crease and sink in; Overlap with the crease and fold hard. Cover folding: fold the crease according to the peak line; Put your thumb on the tip of your heart and press hard with your index finger and middle finger; Fold down along the crease like a lid; Press the crease hard.

Reverse folding: Fold the crease according to the peak line; Insert your thumb into the bottom, put your index finger on the top and fold down along the peak line; Then make a middle fold down the peak line to make it concave; Press the crease hard. Inside out: keep it up and down and turn it over as it is.
