CANVAS-GRAIN CLAY-BOARD.
No. 1. White cardboard, impressed with a [plain canvas grain].
This gives a fine painty effect, as shown in the drawing of polled willows: a drawing made in pencil, with lights in foreground grass and on tree-trunks scratched out with a knife or with the curved-bladed eraser sold for use with these preparations.
PLAIN DIAGONAL GRAIN.
