Note 46 — ELEMENTS OF DRAWING. (continued 3)

A more methodical, though under general circumstances uselessly prolix way, is to cut a square hole, some half an inch wide, in the sheet of cardboard, and a series of small circular holes in a slip of cardboard an inch wide. Pass the slip over the square opening, and match each color beside one of the circular openings. You will thus have no occasion to wash any of the colors away. But the first rough method is generally all you want, as, after a little practice, you only need to look at the hue through the opening in order to be able to transfer it to your drawing at once.
