The Fat Frank Yellow Sallie is a #14 attractor dry fly from Yellowstone Fly Goods, tied to imitate a yellow sallie — the little yellow stonefly. Tagged as a stonefly pattern, its fat, buoyant profile suggests the natural and rides high through riffles and pocket water. The yellow color is bright and easy to track on the water. Fish it dead-drifted when yellow sallies are hatching, or fish it as the top fly in a dry-dropper rig with a small nymph below — a high-floating attractor dry for trout water.
