Have you ever watched a three or four year old play or make art? I do this a lot since my daughter is three. I love to see her get really absorbed, see the way her face changes, her body language. I admire it. I also like to see how she will use anything she can get her hands on and play with it - glue, paint, buttons, sticks. When do we lose this sense of play? This boundless creativity?
It's not so easy to just commit to play, we are conditioned so thoroughly to be a certain way as grown ups that 'adult' has even become a verb! How about using some household items, like children do, and incorporate them into our art journaling.
