Have you seen a Buddha Board?
It’s a board that is covered with what feels like very thin felt.
You paint with water on it.
When it dries, your picture disappears.
It is very Zen.
A friend gave me mine several years ago and I used it for awhile till it was designated to a shelf when the seasons changed.
Then this spring it was found during a housecleaning spree.
So I took it to work.
I like the environmental factor.
I also enjoy watching the children use it.
How they use their body.
How they use the whole board.
How it dries and is ready to be used by someone new.
