Text It is a rectangular box model that is a little different in the way it is folded.

1. Take a square sheet of paper, in a horizontal position.

2. Create a valley fold by bringing the top edge over the bottom edge from top to bottom.
We obtain a rectangle of double thickness, with an upper hinge edge and three open sides.

3. Create a valley fold by bringing the right double edge to the left double edge from right to left.
We obtain a square of quadruple thickness, with a straight hinge edge connecting two flaps of double thickness.

4. Create a valley fold by bringing the left double edge of the top flap from left to right over the right hinge edge. Mark the fold well.

5. Bring the left edge of the lower flap to the right hinge edge using a mountain fold.
We obtain a rectangle of thickness 8, comprising four flaps of double thickness forming an accordion. There are two superimposed left hinge edges and a right hinge edge.

6. Hold the lower left hinge edge between the thumb and index finger of the left hand and the upper left hinge edge between the thumb and index finger of the right hand. Open the shape by pulling to the right.
We obtain a square shape hiding behind it two contiguous vertical rectangular flaps.

7. Bring the upper left corner of the square to the lower corner (45° fold).
We obtain a triangle of thickness 4 bordered on its lower side by a horizontal rectangular flap of double thickness located in front of the triangle and on its right side by a vertical rectangular flap of double thickness located behind.

8. Unfold the two flaps, one downwards, the other to the right.
The shape obtained has on its left a fold-hinge inclined at 45°.

9. Rotate the front flap back and forth several times around the 45° fold, so as to make it very flexible. Finish with the front flap returned to the initial position.

10. Unfold the front flap towards the rear, so as to form the rectangle of thickness 2 of step 2.

11. Unfold the rear rectangular flap so as to find the starting square.

12. Rotate the right edge around the fold located in the right quarter of the sheet, fold created in step 3.

13. Fold the top edge backwards by pivoting around the middle crease created in step 1.
We obtain a rectangle whose right side is bordered by two vertical rectangular flaps located on either side of a rectangle of thickness 2. The upper right corner of the rectangular shape will serve as a reference for the following steps.

14. Slide the index finger of the right hand between the two flaps starting from the right, so as to grasp the lower right front corner between the thumb and index finger and the lower right rear corner between the index and middle finger.
This operation has the effect of opening the shape around the upper hinge fold.

15. Place the index finger of the left hand along the upper hinge fold, without meeting the thumb of the right hand. At the same time, slide the thumb of your left hand inside the double flap, as far as possible while remaining in contact with the hinge fold.

16. By rocking the thumb of the left hand downwards, the fingers of the right hand very freely accompanying the movement, completely open the flap, which flattens into a triangular shape whose apex is located next to the thumb of the right hand and which is bordered at the bottom by a horizontal rectangle. Continue pushing downwards until the two parts of the flap come together. The upper hinge fold of the vertical rectangle must remain horizontal.
We obtain a shape composed of two triangular flapls each bordered by a horizontal rectangle. These two flaps are connected by a long vertical hinge-fold, located to the right of the shape. Each trapezoidal flap has a fold-hinge on the side at 45°. This fold-hinge gives access to a triangular flap, which covers the triangular part of the trapezoidal flap. A hinge fold located on the right, which exactly follows the long median hinge fold, connects the triangular flap to a vertical rectangular flap whose upper right vertex coincides with the vertex of the internal trapezoids. Finally, the two vertical rectangles are themselves connected by an upper horizontal hinge fold. If we move the thumb and index finger of the left hand along the 45° edge, we can slide them under these two vertical flaps which, in practice, encompass the points of the two internal trapezoids.

17. Create a valley fold by bringing the lower left corner of the upper trapezoidal flap to the right edge, making a 45° fold.
The flap that we have just created covers the upper vertical rectangular flap.

18. Slightly unfold the flap that you have just created and slide it under the vertical flap that it covers.

19. Repeat steps 17 and steps 18 with the rear trapezoidal flap, to slide its lower left corner under the rear vertical flap.

20. The upper vertical rectangle is bordered on its left by a triangular point. Fold it into a valley along the left vertical edge of the upper rectangular flap. It partially covers it.

21. Unfold this tip slightly to slide it under the upper rectangular flap.

22. Repeat step 20 and step 21 with the rear point bordering the left side of the rear rectangular flap.
We obtain a vertical rectangular shape ending with a triangular point towards the bottom.

23. Rotate the shape by pivoting around the left edge, to bring it perpendicular to the table.
The shape is now in profile. Open it very slightly, to notice that there are two exterior flaps (one left and one right) and a third interior flap.

24. Take the left outer flap between the thumb and index finger of the left hand, sliding your thumb between the left outer flap and the inner flap. Take the right outer flap between the thumb and index finger of the right hand, sliding your thumb between the right outer flap and the inner flap.
The inner flap is between the two thumbs.

25. Open slightly by pulling on the two exterior flaps. The interior flap tends to stick to one or the other thumb. Continue to pull lightly, to open the starting shape more and more, until you reach the stop.
During this movement, the interior flap tends to deform, then decrease in height. The two exterior flaps begin to form a more or less circular wall around a bowl whose bottom is made up of the more or less deformed interior flap.

26. Once the stretching process is complete, gently push the bottom of this bowl with a thumb to completely flatten the bottom.

27. Finish by shaping the walls.
We obtain a rectangular box, of which three vertical walls are of triple thickness, and one of single thickness. If you use two-tone paper, one side of the box is a different color from the others.
