step
1. Take a piece of rectangular stationery with the ratio of 1: 2 (please ignore the paper here, take local materials, there is no stationery, hehe), fold it in half horizontally, unfold it and leave a crease.
2. Then fold it vertically twice and unfold it, leaving three creases.
3. Fold such a triangle diagonally twice on either side of the rectangle, leaving a crease after unfolding.
4. The center line crease shall prevail, and the other side of the rectangle shall be folded upwards to leave a horizontal line.
5. Then align the upper edge with the horizontal line on the left and fold it down.
6. There will be two small squares on both sides of the top corner, which will be folded diagonally to form two small triangles.
7. Then open the triangle and fold the middle crease inward.
8. The same operation is done on the other side, leaving a small rectangle, and then folding the lower side of the rectangle to overlap. Form two small rectangles.
9. Then unfold the two small rectangles separately and fold them in half with the center line.
10, and then fold the two extra small squares.
1 1. Fold up based on the crease.
12, then fold the lower corner of the heart inward and fold the sharp corner of the heart.
13, do the same operation on the other side, and then fold the two corners above the heart back for a short time to complete a heart.
14, based on the line overlapping the sharp corner of the heart, fold in half.
15, with both sides folded inward based on the crease.
16. Fold the two sides in half, and then fold the center line in half.
17, folded in half at the back of the heart. In this way, a thoughtful letter is folded.
