waterproofing clay pots to fill with water for bamboo
I am making bridal shower favors and would like to fill small clay pots with stones and insert lucky bamboo. The bamboo needs to sit in water, so I need suggestions on how to make the pot completely waterproof as well as a suggestion to plug up the drain hole. I have tried hot glue to plug the hole but I am concerned about it bonding. Do you think I would need to treat both the inside and the outside of the pot? I like the way the pot looks naturally, so I really didn't want to add color. Thanks for your suggestions!
