Step 1: Materials
-Duct tape: grey
-Duct tape: black
-starch paper from a folder or notebook cover
-Tools (scizzors, ruler)
(You don't have to use grey and black duct tape, that's just what I used)
Step 2: Cutting The Pieces
Divide one into 3 strips.
Cut out the 3 squares and the 3 strips.
Step 3: Preparing The Pieces With Duct Tape
Next put the grey duct tape over each of the strips. Fold over the sides.
Step 4: Attaching The Pieces
Now take two strips and attach them on either side of a square.
Attach the third strip to the opposite side of the square from the last 2 strips.
Now fold them all in and place the last square on top.
You can now attach that to the strips. (if you look at it from the side it should form an X)
Step 5: Finishing Up
You can also add more just to thicken it up alittle.
It should look like the last pic on the inside too. (that part is tricky)
Step 6: Finished Product
Step 7: Functionality
When you open it from the left it will appear one way, and it will appear another way if you open it from the right!
