Fig. 20.—Drawing of brushes.

An excellent type of brush is that made of black Siberian bear hair for fine varnishing. These can be had from good brush-makers with the hair fixed so that it will stand soaking in water. Drawings of the type of brush are given above.

Three or four are sufficient; one broad brush, about three inches, for large spaces, one two-inch, and two one-inch, will do nearly all that is needed. Occasionally a smaller brush may be of use.
