If you mean you're looking for a construction method for the headpiece, I'd recommend making an EVA foam base fitted to your head and using a semi-hollow construction of upholstery foam for the overall shape. Cover that in a suitable fabric, preferably one that hides seams and you're golden
That how I do it, anyway. There are countless methods but I like the flexibility that foam has as well as how easy it is to work with! Forgiving stuff, if you chop too much off you can just glue more on and carve it down. Love it
I'm in the process of making this headpiece for a client. Once I'm done I may be able to offer pulls from the molds. It will be a latex skinned poly foam with weighted tail ends for realistic movement. I'll post pics when I can.
