I have recently received some Hends Body Quill material and have been playing on some flies with it. It is easy to work with and comes in a variety of colours. Though I haven't experimented enough I really like this material as you can vary the colour of the bodies by changing the number of wraps. You can also add different colours in your body as seen in the
Red Butt nymph.
Two other flies I have use it on so far.
