Step 1: Inflate the balloon with helium to desired fullness and tie a long string to the base. Trim all the flower heads and greenery.
Step 2: Start by taking some of the greens and fasten them to the very top with floral wrap, tape, or hot glue.
Step 3: Continue by alternating greens with flower heads and make your way down the string.
Step 4: Fill the entire string with the silk flowers! The flower heads will weigh down the balloon, but secure it to something before putting it outside.
