I recently finished a film which required foley for cannibal natives.
I needed foley for shell and bone necklaces.
I had nowhere to turn to,
until a friend of mine discarded his pistachio shell cup!
I was saved!
I bought a bag of roasted and salted pistachios.
Taking a handful, I began to create some very convincing foley for the natives running about.
I'll upload some samples tomorrow with an update to this post.
