As a former Fusilier, here is how I did it. Before Amalgamation we all had a tartan patch on the left side of our T.O.S. in the center of that we made a hole thru patch AND bunnet, push the hackle thru the hole and BEND upwards,then I always sewed the wire to hold it in place, otherwise it can tip sideways. So if I was you I would first sew the patch on and go from there. I hope that this helps you out.
