Choose 10 cinnamon sticks of the same length and thickness. Thread a 40-inch long wire through each in a continuous line. Bend to form the outer 5 star points so that the last stick is joined to the first stick at an inner angle. Twist the wire.
Cut 5 shorter cinnamon sticks to fit the inner pentagon. Thread each stick into place twisting the wire around each intersection. Cut off excess wire and it's ready for your Christmas tree.
