I've done enough research to know you don't want regular old short firework sparklers for an exit, but - brides - did you use 20" or 36" sparklers?? We will have about 165 people for whatever it's worth but highly doubt all of them will be around by the end of the evening. Sites to order from welcome suggestions, too. (I've found some via google but vetted ones would be great so I know they aren't crappy!) Thanks!
