Step 1: Gather All Supplies


Hot Glue Gun

Glue Sticks

Craft Knife (or scissors)



Step 2: Cut the Cardboard

I used a large cardboard shipping box to create the pieces I needed:

One large piece 16 x 36 inches (sides of the locker);

Two pieces 8 x 10 inches (top and bottom);

One piece 8 x 16 inches (for the handle, feet and accessories).

Step 3: Make Body of Locker

Take the big piece of cardboard and draw lines at 8.5, 18.5 and 27 inches from the end (this will make a locker that is 10 inches wide, 8 inches deep, and 16 inches high).

Slightly cut (score) the lines.

Fold along the lines to create a rectangular box.

Glue edge together

Glue 8 x 10 inch pieces to top and bottom.

Step 4: Make Door and Handle

Put the locker on the table with the 10 inch-wide side facing up. The side with glued seam should be on the bottom.

Choose which end is the top.

Place your ruler on the left hand edge two inches down from the top of the locker. From that spot, draw a 8.5 inch line across the front. Draw a similar line two inches from the bottom of the locker. Then draw a line connecting those two lines. Cut along all three lines and fold back to make the door.

Measure and cut a 1.5 x 8 inch strip. Fold it into the handle (see picture) then glue it to the locker.

Step 5: Make the Feet

Cut out eight 2 x 2 inch squares.

Glue them together along one side.

Then glue them to the bottom corners of the locker as shown in the picture.

Step 6: Create Interior Accessories

You can leave the inside of the locker open, or you can make accessories like shelves. In my locker I added two big shelves and one small shelf (for my craft knife or pencil).

To make the big shelves, I cut out 2 squares. The top square was 6.5 x 6.5 inches. The bottom square was 8 x 8 inches. Then I glued two sides of each square to the back left hand corner of the locker.

To make the pencil or craft knife holder, I cut a thin 1 x 7 inch rectangle and glued on the right hand wall.

Let the glue dry.

Happy Organizing!

    Nice simple design and clear instructions. It makes you want to get out the hot glue gun, craft knife, ruler & maker and try one's hand at cardboard recycle. Like the attention to small details in design! Well crafted!!
