Step 1: Getting the Shape
I used a plastic bag.
I wrapped it around my head (but cut the face mask out, so I could breathe)
After the plastic bag is securely wrapped around your head and take the shape of your head, have a friend cover your head in duct tape. to secure the shape.
sorry, but I didn't take any pictures of the helmet with duct tape round, but once you've done that, simply paper mache it all over
you must also add the circle things on the side of his head when you paper mache. those are optional tho
Step 2: The Face Mask
its really good and works
I didn't bother with the lights and stuff
Step 3: Painting
once painted and dryed, add detail with pen. you could do what you want with the design.
on the back i attached a bit of card (inside or out) which will seal the helmet making it a complete helmet.
Step 4: Last Touches
i also attached velcrow to the card at the back which seals the helmet.
