Finishing
Cut 5 strands of A measuring 9 inches each. Hold strands in a bundle; fold in half to form a loop. With the WS of throw facing, take loop through edge of first color A stripe. Take ends through loop and pull up to form a knot. Before tightening the knot, include any color A strands into the bundle. Adding one fringe to each sc stripe and 2 to each dc stripe, in color sequence add fringe across. Add fringe to the opposite edge. Trim fringe evenly.
