Sometimes, particularly with Partridge and hen hackle, the hackle barbs will be too long after you wrap the wing. Generally you only want the tips of the wing to extend just back to the bend at most. The below technique allows you to use bigger feathers and still get the advantage of the feather’s markings. Mallard, Teal, Gadwall as well as Partridge come to mind.
