Thanks to the amazing Amy Locurto for the creative idea.
You'll need the following:
White candy melts
Red and blue sprinkles
Container of some sort
Red tissue paper, shredded
Place the floral foam into the container.
Put sprinkles into dishes.
Melt the candy melts as per instructions.
Take a marshmallow, insert a stick, dip into the candy melts, dip into the sprinkles and insert into the foam. (The Daughter preferred using her fingers to hold the marshmallow when dipping the red/white/blue design.)
Use the red tissue paper to cover the floral foam.
