This is no ordinary wool! Called Mara Wool to convey its incredible mobility in water - rather like that of Marabou. The fibres are straight, translucent and have good length. This material makes for much easier tying of Wool Head Sculpins and saltwater streamers with large heads (eg Wool Head Mullet). Can be coated with Silicone for making the "Pop Lips" type fly as well as some great Bass Flies. A good substitute for Arctic fox as well as being used for making those subsurface flies traditionally tied with Deer hair. Eg Muddler patterns. Tie as per "GloBug yarn in small bunches around the hook shank, then trim into shape.
