I am having a difficult time finding what I want to fill my vases with. I rented a 10" square vase and I have silk orchids I would like to submerge in water with a floating candle on top. I have been looking at glass gems, but they are expensive. I need to fill 30 vases and I would be looking at about $3 per vase to fill. I think this is too expensive. I have considered loose pearls, not sure how that would look. I need clear and light green gems/pearls. Does anyone have any suggestions???
