DIY detailed step-by-step illustration:
Take a square piece of paper with the red side facing up. Fold the paper in half along the diagonal line and then open it. Continue folding the upper and lower sides to form the center line.
After folding it in half, open it and fold the top part down to form a small square. Fold the top and bottom sides toward the diagonal lines of the small square to make creases. After opening, fold along the creases. As shown in the picture. After doing the same on the left side, turn it to the back and continue on the back the above operations. Rotate 180°, fold the upper part down, turn out the small triangle part, and do the same on the back. Turn the upper layer of paper to the right along the vertical line, as shown in the picture. Fold the left and right parts from right to left along the crease. Repeat the above operations on the back and flatten it. Fold the upper part upward along the center of the quadrilateral on both sides, and press out the fold. mark. Do the same on the back, turn the left half to the right along the vertical line, turn the right side of the bottom to the left, turn it over, repeat the above operations, and fold it upward along the center of the left and right sides as shown in the figure. After rotating 180°, turn the above shape over again, similar to step 6, fold the overlapping part upwards, and open it with the crease along the back edge to form a box shape. Turn over to the back, pinch up a corner, and fold theFold the corners toward the bottom of the box on that side to form a downward pointed shape. Repeat the above operation for the four corners. If successful, adjust the shape.Done. Teach you how to make an origami box, how to make a four-pointed star paper box with step-by-step diagram.
