Like this idea - Scan childrens art work and then print out in smaller size. Now make art gallery in hallways of your childrens art:). Awesome idea, even for my grown young adults to have all of the kept keepsakes of their artwork in one frame.
Here's a really cute idea. Frame quote bubbles, use a dry erase marker to write funny things your kids say. When you are ready to switch the quotes, have the child take a picture with their quote and make a photo book of quotes. Cute for school too!
