About a week or so ago, I decided to try and keep art supplies out for A so she could use them whenever she chose to. I made sure to have a piece of paper taped down (with painter's tape) to her small table as well as one on the easel. She's been doing a great job!
The containers are just mini-cans of veggies covered with scrapbook paper. I had the white base from a candle display. We've had a lot more masterpieces around here lately, and I no longer have to get markers or crayons out when A feels like using them.
