What an efficient way to recycle your whine bottles? They will protect candle flames from any wind condition and make it a lot more interesting to look at.
I found this Italian Flint Bottle Hurricanes on Napastyle.com. Unfortunately, they no longer sell these, and alternative designs are quite expensive, so you might have to consider it as a little diy party outdoor lighting project or get someone who is good with glass cutting to get it done, depending on your budget.
However, it will be not easy to cut and polish the bottom edges so they are even, won’t wobble and are safe for handling, unless you know a good glass cutting technique.
