90. For a change dark flakings and other flaked veinings may be put in instead of light ones. In this sort of quartered oak graining the whole thing is reversed. The color is applied evenly but solidly over the panel and immediately combed with rubber combs and split as related in the preceding paragraph; then with the camel hair pencil brush proceed to pencil on the flakes and champs as desired, slightly blending them with the badger blender. This is not so difficult to execute as by wiping out, because it does not matter about hurrying.
91. In either method the use of the check roller can be resorted to to improve the looks of the graining, it is best to delay it until the graining has been completed, as then it can be put only in such parts as really require it, while if put on beforehand it may be that they may be placed where they should not. They are not essential and, as stated before, really a detriment when not used rightly. The expert who knows where to use them, however, obtains a more natural finish by their use.
92. The overgraining ought to be done in oil colors and put on very thinly, then with clean cotton rags wipe it off from such parts that are required to be light, which will give the shading as if it had been done in oil over oil graining with the difference that in shading the latter the overgraining color is applied only where it is wanted and requires no wiping out.
93. Where distemper graining is overgrained with oil colors it practically becomes the same as oil graining and that alone will usually protect it against accidents caused by water washing it off, but as the finish does not look even, that must be supplied as in the previous graining described, by either waxing or varnishing, or a combination of the two as related in paragraph 77.
