Does anyone have any resources for where to find rectangular or oval glass bowls/candle holders to float candles in. I'd like a rectangle 3x3x12ish or an oval 3x6x12 or so. I have only found one rectangle version and it is only 8 inches, which will be too small. We have oblong tables in our hall rather than circles, so I thought oblong floating candle holders would look better, but they are proving harder to find than I thought. There are so many chunky square glass votive holders out now that I thought for sure I'd find rectangles. We would really like to do floating candles so that we can also float our orchid blossoms in addition to scattering them on the tables.
