Most stains will stand some water, but common ink would wash out if rained on. So to preserve the color, checkers dyed with ink should afterward be dropped into a thin shellac and taken out and dried. Those of natural color should also be shellaced as they keep clean much longer. After the shellac is dry, there is a little roughness on the surface. If this is rubbed off with fine sandpaper the checkers are much more agreeable to handle. Twelve checkers of each color are needed for a set but three or four extra ones may be added. Put these in a strong bag securely tied.
II. Button Molds. Instead of using dowels, as just described, wooden button molds may be colored and used.
III. Buttons. Two contrasting colors of flat buttons make excellent checkers.
Problem VII
PICTURE FRAME
Time: 4 hours.
Materials: Newsboard, vellum or paper.
First choose size of picture and then width of frame. This may be uniform on all sides or one may observe the rules for margins shown on pages 21 and 22. Make a careful drawing of the outside of the frame and opening, and then lay out and cut the newsboard as indicated. For covering, plan and cut a piece of vellum, grass cloth, paper or other material which shall extend beyond the newsboard on each side for at least one-half an inch. On this material indicate the position of the newsboard including the opening for the picture. Also draw lines one-half an inch inside and parallel to the lines showing opening. Cut on these lines and at each corner cut oblique lines to allow the laps to fold under. For the back there should be planned and cut another piece of newsboard one-eighth of an inch shorter than the front and of the same width; and to cover it a strip of covering material three-eighths of an inch longer and one-quarter of an inch narrower than the newsboard. (See Plate XXII.)
Plate XXII. Dimensioned sketches of the parts of a picture frame.
To assemble: Paste the foundation of the front to the covering and turn under and paste the laps at the opening. At this time paste only one outside lap and that the top one. Over one end of the newsboard-back turn the outside strip about half an inch and paste this down leaving the remainder of the piece free. Place this piece of newsboard against the front, with the pasted end at the top, and over both pieces of newsboard paste the three laps attached to the front side. Fold back the free piece and paste as a lining over the back. To this may be pasted a patent hanger—a ring attached to a gummed disk. The picture should be inserted at the opening in the top.
