How can I redo 2 sand art containers?
Not necessarily with sand.
Suggested Project Book
Georgia if you want to layer the containers with other items you can fill with what ever you like.
For a layering effect I only know of sand as a layering and design type thing. But you can use natural things like shells, rocks, twigs etc.
The dollar and craft stores have marbles and stones or the flat glass heels used for flowers.
Let your imagination go wild!

Sand art is so fun and there are so many possibilities. Here is one I made for my daughter with a mermaid or beach theme. But you can use any accessories you like. https://ourcraftymom.com/make-fun-beach-themed-fairy-garden/
