I'm sure if you contact confetti cakes she will tell you, she is very nice.

Ok, I have a glass guy. I order so much from him, he charges me like nothing to cut out pieces of glass. So, I like to go shopping at antique stores, craft stores, garage or estate sales and look for large candle pillars with sturdy bases.
I get a glass round or square in the appropriate size, and glue it to the candle pillar. Its pretty much the same concept, and you can find some really neat candle holders in higher end neighborhood estate sales and antique stores in a multitude of colors.
