Hook: Mustad 9049, or any low-water salmon hook sizes 2-8
Thread: grey, brown, or black
Tail: grey deer hair fibers, tied about as long as the hook gap is wide
Body: burlap sack material
Hackle: grizzle, like a wet fly collar
There are other variations on this pattern, one of which can be found at fly anglers online (where the photo above came from).
One reason burlap came into use for fly body material is because you can easily color it along the stream if need be. It's natural color fits the bill for a lot of acquatic life, but if you take along different colors of permenate markers, you can have this fly brighter than a cannary in no time, if you needed to. Plus, burlap is pretty easy to attain, too & cheap. You can't beat that! There are other patterns where burlap has been used & we'll look into those in a later post.
So tied up some of these burlap flies & give them a shot. The steelhead - & all salmon -seem to love them.
