The Masu Box

step 1

Create a Blintz Base

1.1 Fold the paper on the north/south axis. (Your paper should look like a vertical rectangle)

1.1.1

Crease and unfold the paper (Their should now be a fold line running down the center of the paper)

1.2 Fold the paper along the west/east axis. (The paper should now look like a horizontal rectangle)

1.2.1

Crease and unfold. (their should now be two perpendicular lines that intersect in the middle of the paper)

1.3 Fold each corner of the paper into the center of the paper. (After this step, you should have a folded square with 4 triangles on top)

step 2

Fold the Blitz base into a 4 by 4 grid.

2.1

Fold the Blitz base on the north/south axis. (your blintz base should now look like a vertical rectangle)

2.1.1

Crease and unfold. (there should now be a line running down the center of the blintz base.

2.2

Fold the blintz base on the east/west axis. (the paper should now look like a horizontal rectangle.

2.2.1

Crease and unfold. (the blitz base should now be divided into four quadrants.)

2.3 Fold the left side of the blintz base so that the edge meats the north/south crease. (repeat this on the right half of the blitz base as well) (now the blintz base should look similar to a set of closed, double doors(

2.3.1

Unfold the blintz base into 4 vertical rectangles.

2.4 Turn the blitz base 90°, and repeat step 2.3. (the blitz base should now resemble a 4 by 4 grid)

step 3

Finish the box

3.1 Lift the east and west portions of the grid to form two walls. (You should have a a shape resembling a long and short print letter u, with two 4 by 1 walls on either side, and a two by 4 base)

3.2

Feel along the southern triangle, locate the two right triangles on each side, pinch these together with the east and west walls. (The box should now have 3 walls, with two triangular flaps where the walls meet)

3.3

repeat the previous two steps on the northern triangle. (Your masu box should now be done! with four walls and four flaps securing them)
