I was painting the other day and Sadie wanted to paint as well. So I loaded up a plate with some of my acrylics, showed her the cup of water and paper towel blotting thing and let her get to it.
I got an extra 1/2 hour of work done and Sadie had a ton of fun. She painted again the next day. And she's got an easel waiting to get set up for more painting, courtesy of Auntie M and Uncle E. I have no doubt she's going to love it.
