Things You'll Need
Instructions
Draw a circle 18 inches in diameter onto the wood panel. Cut out the circle and sand its edges.
Draw 17 evenly divided vertical lines in pencil on the board.
Draw 17 evenly divided horizontal lines in pencil on the board. You will have a grid pattern with 256 spaces. Some of them will not be complete squares because of the round board.
Draw a large diamond in the center of the board, with its corners two spaces from the edge on the center horizontal and vertical lines.
Divide the diamond along the center lines into four equal triangles. Shade in the horizontal and vertical center lines within the diamond. (The shadings help establish the triangles.) Color one set of opposite triangles -- top left and bottom right, for example -- in red. Color the other set in white.
Draw four right triangles extending outward from the points of the diamond. They will not have flat bases because of the curve of the board. Color each of these small triangles red. Color the remaining parts of the board yellow.
