Bond the 1½-inch circles onto opposite sides of the tepee opening, 22 inches up from the bottom and 11 inches in from the opening edges (on radius marks). Bond the 8-inch circles 10½ inches (on center) away from the little circles as shown.
Cut out twelve 3-inch-tall yellow triangles (see figure D). Cut one triangle in half lengthwise and apply the halves to the two opening edges at the bottom of the tepee; bond. Apply the 11 remaining triangles to the bottom edge of the tepee at the six radius marks and halfway between each pair of marks.
