Leather combs ([Fig. 3]) can be purchased from most of the large dealers in painters' materials, but they are inferior to combs cut from the best sheet rubber. In making the latter choose a piece of rubber measuring about two by four inches and not over a quarter of an inch. Cut the teeth on each of the four inch sides, making those on one side coarse and those on the other side fine, thus you have two combs in one, and by turning over the comb different lines can be made; do not cut the notches of the comb too deep, and leave considerable space for the face of the teeth. A rubber comb can be often used, especially on rough work, without covering the teeth with a rag, as being soft it conforms to the inequalities of the surface, and leaves a more distinct pattern than does a leather comb.
