Step 1: To make a blind box, prepare colored cardboard, scissors, glue stick, pen and ruler.

step 2 first draw a square on the cardboard with a pen and a ruler.

step 3 draw a square with the same size on the left and right sides of the square.

step 4: draw a square with the same size above the square, and draw two squares with the same size below the square.

Step 5 Draw five small trapezoids on the edges of the left and right squares and the bottom square.

step 6: use scissors to cut out the outermost contours of all figures.

Step 7 Fold each line on the graph by hand.

in step 8, surround the left and right four squares together, put a glue stick on the trapezoid, and glue the four squares into the side of the box.

step 9: after putting something in the middle of the box, put glue sticks on the trapezoid of the left and right square edges, and stick them together with the square on the side to form a cube, and then make the blind box by hand.
