Why don't you at least post a link of the fly your asking about?

Rainy's pics are not loading right now... So I'm guessing here.

Looks like it's made from rocks....I made one like this once.. it's a bit of
work.

You can build up the body a bit.. then coat on epoxy.. dip it into small
pebbles and scrunch them into shape.
You can then touch up with epoxy again later and add the peacock herl.

It's a ton of work... and unless you build the body well to begin with it
will all rotate around the hookshank.

Subject says it all. It is a guarded top secret matter, but what is the
body made of of the Rainy's rock and roller? The head is obviously
peacock herl.


Ask her yourself:

She sells fly tying materials, so I doubt it will be too much of a
secret.
