Here is a little history for you. 98 Percent of the Hairs Ear Nymph's tied today are wrong as to the original pattern. They use the wrong hair and are way to light in color. The "Hairs Ear" Nymph is tied from the "Center pole of a Hairs Ear". In other words the salt and pepper area on the outer edge of the Rabbits ear. If you look at a mask it will be the hair on the outside of the ear and this area is to the middle of the mask as you look at it. You scrape it off with the edge of a tea spoon. These nymphs were tied to copy the Beatis nymph and do a great job of it if the right hair is used.
Today most people just cut off all the hair from the mask and the body hair and mix it. Or buy it premixed and it is all wrong, but it is right because that is what people think it should be LOL.
In truth you do not get much of the proper dubbing from a mask. That is why they started using the "Whole Thing" You use the cheek hair for the tail of this nymph. Ron
