First decide on the size of the small squares, remembering that there
are eight in each direction. Also allow for a margin, outside the
squares, which should vary in proportion to the size of the squares.
A single or double border line enclosing the squares is a desirable
addition. (See B, Plate XIII.)
Make working drawings of the foundation, the front covering of vellum,
and the back covering of lining paper. In selecting vellum for this
model, have in mind the application of a color which is to be used on
alternate squares. Either a deep red vellum with alternate squares of
black or a dull green vellum with alternate squares of red is a good
combination.

needlecase, and dimensioned sketches of the pieces used for covering.]
Lay out and cut all parts, using the card cutter for the newsboard,
and the scissors for the vellum and the lining paper. As in previous
models, lay foundation on the back of the piece of vellum, draw around
it, and cover with paste the surface enclosed by the pencil lines.
Again place the foundation on the vellum, press it down hard, turn
over both pieces and rub the vellum on the right side until it is
smooth. When thoroughly rubbed down, paste laps, being careful to make
neat corners. Paste on lining paper and dry under weight.
During a subsequent lesson, mark out the checkerboard, accurately,
with rule and pencil. Only alternate squares need be colored, and this
may be done with water colors, crayon, or pencil. If water colors are
chosen, they should be used with as little water as possible. Before
applying the paint to the vellum, the glaze of the surface may be
reduced by rubbing over it the powder which comes from common white
chalk. Rub the powder in with the fingers and lightly brush off what
remains. On a separate piece of vellum, practice the application of
color before applying it to the checkerboard, both to test the color
itself, and to become somewhat familiar with the best method of
application. After the paint is thoroughly dry, the surface may be
cleaned by rubbing carefully with a piece of cloth. Finish by putting
on the outside border line with pencil.
