nice pattern! i tied a similar fly, sorry no pics, but i used goose biot for the antennae, tied in at the bend, a little frost bite for the head peeking out, and some dubbing for bulk, then added a good dose of zap a gap,let stand for a minute, i already had taken tiny gravel from a river i stored in a plastic baggie, drop the fly in the bag, shake like you were makin' fried chicken, and presto! you gotta cased stone.
Thanks Guys. I can't take the credit for this one. Part of the pattern came from Oliver Edwards, and the idea of model railroad ballast came from another fly fisher. Instead of Zap-a-gap, I used 5 minute epoxy. Works pretty well here on the Nisqually by my house. I matched the color of the natural river sand with the ballast. I tried using river sand but managed to bring some critters in the house. VEE was not a happy camper.
