Cardboard Boxes
A clean liquor carton with its dividers intact is a great place to store rolled-up posters, drawings on paper, and canvases. Just insert the items upright between the partitions.
Cardboard Tubes
You want to save some of your kids’ precious artwork for posterity (or you don’t want it to clutter up the house). Simply roll up the artwork and place it inside a paper towel tube. Label the outside with the child’s name and date. The tubes are easy to store, and you can safely preserve the work of your budding young artists. Use this method to hold and store your documents, such as certificates and licenses, too.
Hair Spray
Picture this: Your preschooler has just returned home with a priceless work of art demanding that it find a place on the refrigerator door. Before you stick it up, preserve the creation with hair spray, to help it last longer. This works especially well on chalk pictures, keeping them from being smudged so easily.
