Step 1: Obtain cardboard for the pieces.
I had intended just to do a simple cutout, but then I decided to do retractable wings.
Lay out the pieces and cut them into the following pattern. Make sure the wings are going to fit inside the folded piece.
Step 2: Reinforce areas with duct tape and add hinges
To make the hinges, put the wings in place (make sure they work first) and simply poke some scissors through. I made two holes in the main body and one in the wing. I threaded it through like the picture below.
