Take a bunch of Marabou. To remove the bulk / fluff from the marabou, place the marabou tips in your left hand between index finger and thumb and with the right hand move your thumb and index finger nails down the marabou stripping the webby marabou bulk off the stems. Now to make the marabou easier to tie in, I tend to wet the remaining marabou stems and pull it between the index finger and thumb to make a slim profile.
Take a length of lime green chenille and strip about 10mm from the central core of the chenille. Catch the core onto the hookshank and return the thread to a position roughly 1/3 of the hookshank length from the eye.
Wind the hackle down the hookshank in open and even turns. When you reach the lower end of the hookshank ie. Where the tinsel is tied in. Take hold of the cock hackle with your left hand using finger and thumb or hackle pliers and hold the oval tinsel with your right hand. Keep the hackle taught horizontally and wind a rib with the tinsel back up the hookshank trapping the palmered hackle in as you go. It helps if you move the tinsel from side to side as you wind on the rib, this prevents having as many hackle fibres trapped under the winding. If you still find that too many hackle fibres are trapped , just use a dubbing needle to pick the trapped fibres out.
Wind the thread up to the eye. Now continue winding the chenille towards the eye and secure with thread, trim any waste chenille and create a neat head, whip finish and varnish. (To keep the bulk down for the head, I usually strip chenille from the core and secure the core to the hookshank rather than the chenille itself).
