Sure, we can draw on the driveway

Why not?  It's fun!  Sometimes the neighbor kids even come over and join us.  Daphne has a blast.  She loves to draw off of paper.  My little artist feels so constricted with just being able to draw on paper in the house.  Thankfully we have magic erasers when she manages to hide a crayon and get it out when I'm not looking.  When she's outside with chalk, she has free range to draw...as long as it's not on the cars or in the road.  She loves to have me trace her on the driveway.  Sometimes she will draw clothes on her outlines...otherwise my driveway looks like a crime scene.
