One of De is Moss’s top Sedge patterns. He states ” I originally tied this pattern to represent the Murrough on Sheelin, where on a size 10 hook it proved effective during the late evening when the large sedges emerge. Since then I have found this pattern in sizes 12-14 to be good during hatches of grousewing and silverhorn sedges ”.
