Very nice tutorial by Philip Bailey (Yorkshire) at FlyFishWithMe re the L’Ombra (Shadow) pattern. Nice pics to aid in the fly’s creation and how the hook is presented vertically as opposed to horizontally or perhaps diagonally (emergers). The L’Ombra, here, is tied on a Partridge hook. Also, of interest is an ‘umbrella hook‘ reportedly available at Swede’s Fly Shop (Spokane, Wa.) that appears to be suitable for this same vertical presentation.
