I went back and forth with lots of ideas, but when I saw these large white lanterns at Ikea, I was sold! They were a bargain at $14 each, could be reused or sold after the wedding, and would complement our venue nicely. Because the venue was on a waterway with a lighthouse out front, the nautical look of lanterns was perfect!
I had nightmares before the wedding that my dress would somehow catch on fire (maybe after melting my dress fabric scraps to make the ring pillow?). Between that and my theme of reusability, I went with flameless, battery-operated candles to go inside the lanterns. Those babies can be pricey!!! A recently-married friend graciously gave me the ones from her wedding, and I got the rest for $3 each at Christmas Tree Shops (thanks Sarah!). Now they're all over our house, providing a soft (and safe!) glow.
I added a chrome coral to hold the table "numbers". I talked about the DIY for those last year. After the wedding, I sold them on Etsy for a profit. The table names were streets in Charleston.
