Hi, All! My fiance and I are looking into doing our own centerpieces. Our idea is something like the picture attached. Does anyone know of a good website to order vases and/or shells in bulk? Also, what's the best way to put a candle in the sand? I could just see the melting wax and sand not really going well together. We though about going with flameless candles, but didn't know if the sand would get into them and ruin them. Any thoughts? Thanks ladies!
