Wow, I came across this and was shocked, maybe I am nieve but I didn’t know this is how people did it. What a great idea! I know I am writing about this on the Wedding blog, and most people have their own photographers for that but Engagement and save the dates are usually a DIY photoshoot and these would be perfect.
I am considering grabbing these for our Indian themed party where sparklers play an important role. You can purchase this pack of overlays via Etsy.
