You need a large handkerchief. Make a loose fist and drape the handkerchief over it, as shown in diagram A. With your other hand, pull one of the front corners of the handkerchief up between your first two fingers. That's one ear. Now do the same with the other corner, pulling it up between the second and third fingers. Two ears. Wrap the two back corners around your wrist, and you have a bunny with floppy ears and a wriggly nose (your second finger inside the handkerchief).
