Working in a well-ventilated area or outdoors, cover your work surface with newspaper. Place each bell on the end of a bamboo skewer and push the other end of the skewer into the foam block, spacing the skewers apart so the bells do not touch each other.
Remove one skewer-bell from the block, and spray the bell with gray primer. Place the skewer-bell back in the block and repeat with remaining skewer-bells. Allow to dry. Check bells and spray again if needed to cover. Allow to dry.
Using flat brush, paint each bell white. Allow to dry. Dip stencil brush in red and tap brush on newspaper until almost dry. Referring to the photo, dry-brush red on two adjacent ends of the X opening on the bottom of each bell for the mouth.
Using liner brush and referring to photo, paint each nose orange. Outline the bottom of each nose with black. Dot eyes and paint eyebrows black. Allow to dry.
Spray bells using clear spray finish; let dry. Spray bells again using fine clear spray glitter; let dry.
Cut a 3-inch length of wire for each bell. Thread one end of a wire through opening on top of each bell and wrap end back around wire to secure wire to the bell. Shape opposite wire end into a hanging hook.
