Making Up:
Sew a small flower to the middle twisted stem you have created.  Add a butterfly button.  Oversew the row ends and turn inside out.  

These work really well with anything that may be beside a flower.  Perhaps a cat, rabbit, ladybird, dragonfly, tortoise, horse, bee etc.
Have a look here for the butterfly buttons
Have a look here for the flower trimming, or you could use a sequin
