We've done non-messy painting before and it is always worthwhile revisiting.
I covered the table with a transparent shower curtain and squirted paint on it
then I covered it with a clear shower curtain.
The children were encouraged to pat, poke and move the paint with their fingers.
Each day I lifted the top curtain and squirted in more paint.
One more day and we'll lift it off and hang it on the wall.
Our big buddies stopped in for a tour and they loved this idea.
It may be an idea we try, on a smaller scale, with our big buddies at a future date.
