I posted this on the DIY board, but I'm not sure if it's considered DIY. Anyhow, we want to do the sand ceremony and I'm not sure how to go about it. We would like to just pop in at Hobby Lobby and find some vases that we like instead of buying a set online. Does anyone have any suggestions on vase sizes? Anyone tried the wax on top to seal the sand? Did you practice to know how much sand to use/get? Any help would be appreciated. TIA!
