Pyrotechnics
Sparklers continue to be popular for grand departures. If you decide to use them they should be packaged for quick distribution and a way to light them! Stick 2 or more in a match box (or secure with ribbon) that matches your color scheme. I LOVE these match books/boxes/pouches from 2 Pyromaineiacs, Inc.
