Seeing these images on Etsy reminded me of this wonderful and beautifully unique way to light a space: origami balloons on Christmas lights. Love it!
I haven't seen this idea in years.
If you're interested in DIYing your own set of lights, I found a great tutorial here.
This project could be incredibly tedious or it could be a great opportunity to invite a bunch of friends over for an origami party. The more hands on deck, the faster this project would go. At your wedding, your friends would probably have fun pointing out the lights they made.
Plus, these lights would be fun to whip out and hang up for years of post-wedding parties. Another decoration for life!
