Whilst still keeping the hackle taught, take the oval tinsel and wind it up the hookshank securing the hackle as you wind. If you rock the tinsel from side to side as you wind, it will prevent the majority of the hackle fibres getting trapped. Secure the tinsel and trim waste tinsel at the head end and waste hackle at the tail end.
Now catch in a brown cock hackle for the head hackle. The barbs on this hackle should be considerable longer than the hackle used for body hackle, each tyer usually has their own preference on length of barbs to be used. Wind the hackle towards the eye, each turn in front of the previous one. Secure the hackle and trim any waste.
