They have a base layer of 5-6 oz shoulder then 1 layer of 1/5-2 ounce red buffalo calf and a layer of 1/5-2 ounce calf on top with the cutout.So when I fold it over, I don't want just the layers of calf holding the hardware which is why I skived the base layer about in half at the fold. I tapered the skiv, but maybe I should do it more like a step?
