You want the brush which you used in the first instance to paint it with, and that has already been described; but you also want points of various fineness to etch it away with where it is too thick; these are the needle and the stick (fig. 24); any needle set in a handle will do, but if you want it for fine work, take care that it be sharp. "How foolish," you say; "as if you need tell us that." On the contrary,—nine people out of ten need telling, because they go upon the assumption that a needle must be
sharp, "as sharp as a needle," and cannot need sharpening,—and they will go on for 365 days in a year wondering why a needle (which must be sharp) should take out so much coarser a light than they want.
Now as to "sticks"; if you make a point of soft wood it lasts for three or four touches and then gets "furred" at the point, and if of very hard wood it slips on the glass. Bamboo is good; but the best of all—that is to say for broad stick-lights—is an old, sable oil-colour brush, clogged with oil and varnish till it is as hard as horn and then cut to a point; this "clings" a little as it goes over the glass, and is most comfortable to use.
I have no doubt that other materials may be equally good, celluloid or horn, for example; the student must use his own ingenuity on such a simple matter.
How to Complete the Outline.—With the tools above described complete the outline—by adding colour with the brush where the lines are too fine, and by taking it away with needle or stick where they are too coarse; make it by these means exactly like the copy, and this is all you need do. But as an example of the degree of correctness attainable (and therefore to be demanded) are here inserted two illustrations (figs. 25 and 26), one of the example used, and the other of a copy made from it by a young apprentice.
