coloring on demand

Do you remember back in the olden days when we had coloring books? I doubt if my kids will ever get very many of those "antiques" thanks to the convenience of print-as-you-need-them coloring pages. My go to for getting the kids out of my hair so I can work a minute are these Cinderella ones. There's also these nice dinosaur pages for those with Y chromosomes. Once again I'm so grateful to be living in the age of the internet.
