Every home with kids needs one! Especially now that summer is here. It should have:
pens, pencils, crayons, markers, pencil crayons
paper! - wallpaper/wrapping paper scraps, construction, lined, plain white, old magazines
paint and brushes, glitter
bits - empty spool of thread, paper clips, buttons, popsicle sticks, lids, magnets...
By no means is this list all-inclusive. Kids are creative and will use all the resources and materials they can get! So before you throw something away, consider it for your craft bin. It also might be a good idea to keep some rags, old newspapers and other mess-containing items nearby.
