I'm so excited that I found the summer bucket list idea on Pinterest! I always have so many ideas and find some many great ideas, but I find they never get done - but this summer they are! I went out back to our rock bed and found four large rocks. I just used basic kids paint and let the kids make their masterpieces. It kept both of them busy for about 20 minutes, which - if your a parent, you know this - IT'S A LONG TIME!
FYI: We don't use paint shirts in our house, we paint shirtless.
