Start by crocheting a small spiral circle using beige or pink thread, depending on the animal’s body color (pig, cow, horse, or lamb).
Crochet small shapes for the eyes, nose, and other features. For example, use black thread to crochet small ovals for the eyes and attach them with hot glue. Then add a small, rounded piece of thread for the nose and glue it in place.
For the horse and cow, crochet ears using the brown and black thread, respectively. Then attach them to the sides of the face. For the lamb, crochet white thread to form the flowers that will frame the face.
Use black thread to outline the animal’s face and add additional details like whiskers for the pig or a small mane for the horse.
Once all the facial features and decorations are securely glued, attach the brooch backing to the back of the animal’s face using hot glue.
