To put a bristle on a waxed thread, as used in shoemaking. D shows the bristle split, and the end of the taper of the thread in the crutch of it at E. Hold this point between the thumb and linger of the left hand, so that it does not pull out at the bottom F while the two are being twisted together with the thumb and finger of the right hand. When twisted, still hold them firmly at E, and put the bottom F between the little finger and the next finger. With the right hand twist the other portion of the bristle-that is, the top F. Then put the two F's together, hold them with the right hand and let go with the left, and D and E will twist of their own accord. Then fasten the ends at F so that they cannot untwist, as in the adjoining sketch. Take G as the thread or waxed end, and through this make a hole between F F and E, but very near to FF; then take D and pass it through this hole. By pulling D, E will also pass through the hole - in fact, all the bristle except the two ends F F; that portion of the thread will also pass through that has been twisted in with the bristle.
