Here is a pict of a head I made that incorperates a moving jaws with no hinges, where the bottom jaw is totally detatched from the upper jaw, except for elastic. And the wearer's jaw fits on top. It is simple and gives good results.
But I would like help regarding how to fur this area. Or in changing the design so I can fur it and make it look seamless when opened.
The problem being that I cannot glue or otherwise attach anything to the elastic, or it will not stretch anymore. But if I fur only to the edge of the jaws, it sometimes leaves a pretty noticable gap when the jaw is open.
And, although I have only tried this my pinning the fur on, I assume that gluing one piece of fur over the divide will not work as it is not stretchy enough. And, if I leave it looser, it would give the costume baggy 'jowles'.
I've managed to fix things up in the heads I have made, doing whatever works best with each one, but it takes a bit of time and effort to figure out how to best disguise this gap, with out sacrificing jaw movement, and I'd like a more foolproof way of doing things.
The only really foolproof idea I have come up with is to fit the lower jaw inside the upper jaw, so there is no gap, even when open, but this potentially creates new problems in function and design.
All ideas (or even half ideas of simply bits of thoughts) are welcome :)
