When I was a kid, my mom made a bunny corsage for me to wear to church every Easter -- matching poufy dress included. Now she makes them for my niece and nephew.
They're quick and easy to make. Just grab an artificial carnation or rose, then hot glue eyes, nose, mouth, and whiskers on. Use pipe cleaners to make ears, and you can fasten the ribbon bow with wire, then wrap it around the flower stem.
These can be worn around the wrist using elastic as the base, or worn as a boutonniere fastened with a pin.
