With the pin of the pin back pointed down, glue (hot glue works here also) one large button at the bottom and the smaller button directly above the larger one.
While glue dries, cut out a small top hat from the green felt, approximately 1″ wide and 5/8″ high. Cut a small bow tie from the red felt, approximately 6/8″ wide. (Feel free to reverse the colors.)
Carefully glue the hat to the top of the small button and the bow tie between the two buttons. Glue a small green bead over each hole in the buttons, forming eyes and “coal” buttons. A toothpick may be helpful in placing a dab of glue over the small holes. Glue one green sequin to the center of the bow tie.
Allow to dry thoroughly before using.
