I saw some interesting tutorials on making props and costumes with hot glue and cardboard so I decided to try it out. The Witchking Helm has been on my build list for a long time and its simple shapes seemed doable in cardboard.
I used wooden dowels sharpened on the belt sander to make the spikes.
To get a rough forged texture, I coated the cardboard with Bondo filler.
I sanded the surface mostly smooth, leaving voids exposed to simulate corrosion or damage.
I glued on the spikes with a dollop of hot glue.
I used epoxy putty to make the base of the spikes, texturing the putty with coarse sandpaper.
I painted a base coat of black over the entire helm.
I used an iron based paint, leaving black exposed in the recessed areas.
I went over the helm with a wash of black to accent the recessed areas more.
A final drybrushed coat of silver pulls it all together. Edges are hit with a highlight of silver to simulate scuffed metal.
The final helmet modeled on my head casting. I made a black hood to be worn under it hide my face. Visibility is not too bad.
