5 clear acrylic pieces to make a round Sunburst. Set F is our first design-specific template set. With it, you can make a 10 1/2" pieced Sunburst circle to applique to a 12" (finished) square. The 60-degree diamond can also be used for Baby Blocks and Six-pointed Star patterns. Like all of our template sets, Set F includes piecing instructions. Set F also includes a slick freezer paper method to machine appliqué the pieced circle to the background square.
