We had such a good time with the kids when we went to the Children's Museum with them. Abby was quite taken back that everybody was painting this car!! She didn't want to get any paint on HER of course, but she finally got into putting some on the car!
I used the cute kit Butterfly Kisses from Pixel Perfect Designs that you can find here: http://www.polkadotplum.com/shoppe/product.php?productid=19068&cat=0&page=1
