With all of the budget planning that goes into making a wedding beautiful, it's so easy to look for little ways to save money that aren't obvious to your guests. This is NOT the time to do that.
Different than the Fourth of July sparklers you are probably used to, wedding sparklers are usually sold in 3 different sizes - somewhere around 12 inches, 24 inches and 36 inches. The 12 inch sparklers are by FAR the cheapest and initially the most appealing however sparklers burn at a rate of 1 foot per minute - so 3 minutes total for even the longest sparkler. Unless you have an extremely small, intimate wedding, you're going to need every second you can get to have all of those sparklers lit and guests lined up and ready to go!
I always suggest the 36 inch sparkers for my clients. To create that Pinterest picture you've seen time and time again, the sparklers need to be somewhat close to the newlyweds. The 36" sparklers allow both the guest and the happy couple to be a safe distance from the fire in addition to that extra time it allows for more photos!
As you can imagine, there are venues don't feel 100% comfortable with guests who have been drinking for hours waving around sticks with fire on the end of them. Who could blame them?
Before you buy anything, make sure to check your venue guidelines on open flames and ask which areas of the venue (if any) you can have your grand exit! Some venues located within or close to a forrest or another highly flammable area might not permit this at all, unfortunately!
