Over the years, I’ve tied lots of extended-body flies, but really with only marginal results. Usually, it requires twists of Antron, lots of head cement or UV resin and, frankly, a little luck.
Above, watch as Tim Flagler of Tightline Productions ties a simple extended body for a fairly typical mayfly pattern with relative ease. You may have to dig out one of those old hotel sewing kits you kept “just in case,” and you’ll need some stretch tubing to bring it all together, but once you have all the needed ingredients, this endeavor should no longer be an issue of luck.
Check it out and see for yourself.
