This would've been the perfect project for Alexis to work on last year when my kids were taking swimming lessons. We had a 1 1/2 time slot to fill after she was done with her lessons and then Andy had his lessons. We took a backpack with coloring books and crayons.
This would be a great project for long car trips!

Again, it would've worked when we moved from PA to NC and the kids were always looking for something to do. Once we arrived at the hotel, we could've washed them and they could've colored them again!
Great idea!!
