Ring rubberbands around glass vases / candle holders. Spray paint frost. Remove bands. Love it! I think it may be pretty sweet to do this for favors, but instead of using votives, pour candle wax inside and make candles with these.
Cut the bottoms off wine bottles to use for candle covers, keeps the wind from blowing them out when outside
Have guests use Instagram to share photos from your wedding day with a specific hashtag. What a fantastic idea.
