Interestingly enough, the colorful veggies that are so good for you to eat also make great painting subjects!
On another note, these last few weeks as I finished up my studio work, I listened to Luncheon of the Boating Party by Susan Vreeland which I borrowed from my local library. While I did not need an incentive to get to my studio to paint (I had a show deadline!), audio books make a great studio companion when you want a change from music. It was a great story and I love art history.
Another study for my Square Foot Garden series. It has been very helpful for me to draw thumbnails and paint small studies before working on larger pieces. It's a great way to get loosened up and try new things.
