My fiance and I are combining colored sand in place of the unity candle at our ceremony but are having trouble finding vases to put the sand in. Does anyone have any ideas for where to find a glass container to put the sand in that has some way to close the container, such as with a cork or stopper? I've found some on wedding sites but they're ridiculously expensive and we're trying to find something around $20 - $30 or less.
