Kissing balls are beautiful and very easy to make. If you want it to last indefinitely, use silk or artifical flowers and greenery. Start with a 10′ diameter foam ball, and spray paint it green. Select the flowers you want to use. You don’t have to, but I use a glue gun on the tips of the flower stems before inserting them into the foam. Cover the ball with the flowers and greens. At the top add a length of ribbon for hanging.
