The X-wing pilot Poe Dameron is the coolest new character in Star Wars: The Force Awakens. Here you will see how to make his X-Wing pilot helmet cheap.
You will need a bike helmet, paint markers, sharpies, foam sheets, cardboard, duct tape, washers, wooden sticks, small rectangular wooden pieces, silver metallice spay paint, and black spray paint. First cover the holes in the top of the helmet with duct tape. Hot glue some circular pieces to the helmet.
Most of the project is trial and error. You will need to rework pieces of the helmet to get it exactly the way you want it.
