If you're going to make a real-life Skyrim helmet, you're all in, man. You might as well document the process. Volpin Props made a video showing the process.
Commissioned for Dragon*Con 2012, this helmet was built to accommodate and accent the owner’s beard first and foremost. Originally the client had wanted the Iron Helmet from Skyrim, but changed his mind to the piece seen here in favor of the large upturned horns and scrollwork. Like the Female Ancient Nord Helmet, this piece was constructed with aluminum cold casting and rusted ferrous powders to enhance the realism of the castings.
