Paint the mason jar with red glass paint, starting with a thin layer and building up. Let dry completely between layers until the entire jar is covered.
Cut black glitter ribbon to fit around the center of the jar. Trim if needed.
Glue the ribbon down around the jar using craft glue. The ribbon doesn't have to meet all the way - you'll be covering the seam.
Cut a small square of gold glitter foam or felt to act as the belt buckle. Glue down and let dry.
Cut a small square of black glitter ribbon to fit inside the gold foam. Glue down and let dry.
Glue small black buttons to the front of the jar; two above and one below. Let dry before replacing the lid on the jar.
