Wrap forward and tight on the shank with the marabou. It is best to pull the feathers back with your left hand while you wrap. This will keep you from hiding them in the body of the fly and fouling on the tip of the hook.
Repeat this until you reach the front of the hook and then tie off your thread.

Good luck and watch for more tips in the coming months.
