Frames for square shades should have wire uprights at corners.
A square shade is the proper thing to use on a lamp with a square base. This is usually covered with four separate pieces laced together at the corners and the top and bottom.
PROCEDURE 1. Cut four sides. 2. Draw outlines in waterproof ink and color as above. 3. Punch holes ¼ inch from edges. 4. Holes on sides should match to make a neat lacing job. 5. Lace all four side pieces to the top. 6. Clamp lower edges and lace the corners. 7. Lace bottom edge. 8. Give entire shade several light coats of clear plastic spray. Use a ⅛-inch paper punch.
LAMP SHADES
Since shades, in order to harmonize with Kachina doll lamps, cannot be bought in stores, they will have to be made. There are three types of shade that will look good: the cylindrical shade; the conventional round, tapered shade; and the square shade. Round shades should be selected for round bases, and square shades for square bases.
Use smooth three-ply drawing or bristol board, and transparent water colors are better than poster colors.
Shades can be parchmentized by applying a mixture of one part turpentine and two parts mineral oil. Apply the mixture to both sides with a wad of absorbent cotton, and wipe off the surplus. This is done after the shade is painted and glued together, since glue will not adhere to any oiled surface.
I prefer to leave the paper white, just giving it several light coats of clear plastic spray to prevent soiling.
