Step 3Form the helmet's shape and profile
Rough it out (images 1-3)
I sketched out a few ideas of what I wanted the helmet to look like (I should have looked at some real images on the web) and cut out a few pieces of cardboard. I taped these in place to get a feel of what the sizes would be like.I'm a firm believer of test-fitting with tape, then secure it permanently.
Get started, get gluing
After I knew what shape I wanted to create, I curved a piece of cardboard so it fit most of the way around the circumference of the helmet. (images 4-8)I wanted this to fold over and act as the curved section of the helmet. I cut long slits down the center of it so I could curve it and fold the flaps over. (image 4)
Other points
One crucial point in forming the shell is to flatten the cardboard as thin as it will go, this will allow you to mold the curved shape into the paper. If you don't, you'll end up with a folded (and creased) piece of cardboard. (image 4)Pay attention to the direction of the corrugation (the lines) in the paper, this will help keep your cardboard smooth and crease free. -- Creases are ugly. (image 2)
I used my shins to make the main curve of the cardboard. Use anything that will sufficiently and easily curve your cardboard. (image 8)
Use hot-glue. Anything else is a waste of time. It's fast and perfect on cardboard.
