Use the fondant hearts or Sweethearts candies to form eyes, the gumdrops or Cupid Corn to form a beak, the red hots or jellybeans for the feet, and place a candy heart in the center of cookie. Place a small dot of royal icing in the center of each eye. Arrange the candy confetti or dots to form the pupil of the eye. Let cookie dry completely before packaging.
