A decorative beach themed incense burner.
I have not yet done this project myself yet but I plan on it soon enough. I'm just using pictures I found online to try to get my idea out clearer.
If you can find a shell that is big enough you could substitute the bowl with a big shell.
You could also probably use small tropical flowers for decoration along with the little shells.
You don't have to do a beach theme either. Maybe a desert theme and plant some cacti in your decorative bowl? It's all about creativity!
Whenever you want to burn stick or cone incense just stick it into the sand. Make sure that the all of the ashes are landing in the sand so that you don't leave such a mess. It's probably a good idea to change the sand every once in a while.
The scent I would recommend while using it would be "Sex on the beach" of course!
