Fly Tying- a DIY knotted Leg Tool

i haven’t tried this yet but this little home-made gizmo found on In The Riffle’s Fb page gets a doubleplusgood for creativity and ingenuity. how does it stack up to pre-existing leg-knotting options is anyone’s guess which i suppose will be more down to personal preference rather than all-out efficiency but variety they say, is the spice of life or, as Americans would have us believe the popular (yet completely unheard of in France) french term: Vive la Différence !
