Buoyant closed-cell foam offers maximum flotation on large bulky dries that can't be floated well with hackle. Examples include hoppers, stoneflies, cicadas, hexes, and wasps. Great for dry fly bodies and gurglers. These materials are incorporated into many modern steelhead waking flies. Try gluing strips together for stacked body hopper/attractor patterns. Can be laminated for larger popper bodies. 3mm
