For a little over 30 bucks you can get all the vases you need for your centerpieces. All of them. Collect wine bottles from friends, family, and restaurants and you can make these:

You can also make hurricane vases and candle holders using the same bottle cutter. You can also buy bottle cutter from here.

I think they would incredibly cool in groups of 3 or more. I’d love to take one home if I were a guest!
