Material preparation:
Cardboard or colored paper, double-sided adhesive tape, ruler, pencil, scissors, origami stick, etc.
Production steps:
1. First, cut the cardboard or colored paper into a square with a side length of X. If you want to make a square carton with a short side of 5 cm, the side length should be 10 cm.
2. on the four sides of the square, mark the position away from the side y. If you want to make a square carton with a short side of 5 cm, then y should be 1 cm.
3. Fold the square along the marked position to form four sides and four corners. Then flatten the crease with an origami stick to make the paper smoother.
4. Fold the four corners inward along the crease to form a small triangle. Then fold the bottom of the triangle inward to form a small rectangle. Fix small rectangles on the four corners of the carton with double-sided tape to form the bottom of the carton.
5. Fold the four sides inward along the crease to form four small rectangles. Then the bottom of the small rectangle is folded inward to form four small triangles. Fix the triangle on the four corners of the carton with double-sided tape to form the top of the carton.
6. Finally, fold the four corners of the carton inward to make the carton stronger.
Precautions:
1. When making cartons, make sure that the creases are accurate and smooth, otherwise it will affect the aesthetics and practicality of cartons.
2. When fixing the position of small rectangle and triangle, we should keep symmetry and balance to make the carton more stable.
3. If the paper is thin, you can fold several layers of paper to enhance the stability of the carton.
In a word, it is not difficult to make a square carton, just need patience and care. With the accumulation of production experience, you will find that the cartons made are more and more beautiful and practical.
