1. Butterfly. Yellow and black crayon. Vary by using any single crayon with black.
2. Dish. Red crayon, blue and green crayons for back and foreground. Vary by using the two opposites of any color chosen for the dish and omitting the two neighbor- ing colors. See No. 4.
3. Hiawatha’s canoe. Yellow crayon, with rim and name in green. Vary color of canoe, keeping the rim a neigh- boring color. ‘See No. 4.
4. Color-circle. Gray crayon for centre, and five crayons spaced equidistant. This gives the invariable order, red, yellow, green, blue, purple. Never use all five in a single design. Either use a color and its two neighbors or a color and its two opposites. By mingling touches of any two neighbors, the intermediates are made and named yellow-red (orange), green-yellow, blue-green, purple-blue (violet), and red- purple. Abbreviated, the circle reads R, YR, Y, GY, G, BG, B, PB, P, RP.
5. Rosette. Red cross in centre, green leaves: blue field, black outline. Vary as in No. 2.
6. Rosette. Green centre and edge of leaves, purple field and black accents. Vary color of centre, keeping field two colors distant.
7. Plaid. Use any three crayons with black. Vary the trio.
8. Folding screen. Yellow field (lightly applied), green and black edge. Make lighter and darker values of each color, and arrange in scales graded from black to white.
9. Rug. Light red field with solid red centre, border pattern and edges of gray. This is called self-color. Change to each of the crayons.
