adapted from this pattern...
i changed the shape of each petal to have two lobes each, and flipped the flower over, preferring the shape of the bottom of the flower for the clover.
you will need:
needle and thread
cut 4 leaves in the shape shown above. mine measured about 3/4 of an inch tall, and nearly an inch wide.
sew the leaves together as shown above, and tie the threads together tightly at the ends.
sew to a barrette, and clip on your little lucky charm.
