Rh operation. Dip just the point of the brush in the varnish. Use the brush lightly first one way and then the other, finally drawing it lightly in one direction to smooth out the brush marks.

Another little point which seems so obvious as to be hardly worth mentioning is to take care that every part of the surface is reached by the varnishing brush. To ensure this is much more difficult than would appear at first sight, because the varnish is almost colorless, and when one looks directly at the surface it is almost impossible to see which, part is varnished and which is not. It is easy, therefore, to skip a small portion of the surface without noticing it. The only way to provide against this is every now and then to look at the surface from a point at which the light reflects when the lines between the varnished and unvarnished surface will be readily discerned.
