Great Use for Packing Paper
I've found that a lot of delivery boxes have been using long pieces of crunched up paper as a packing cushion these days (thank goodness, so much easier to handle than those packing peanuts!).
Anyway - it makes a great arts & crafts surface for messy projects! I spread a big sheet out on the table, and then let the kids go to town. All the mess of glue, markers, glitter, fingerpaint, etc.. is a snap to clean up because you just roll it all up and throw it away.
Great tip, but be sure to use the packing peanuts for crafts too! They glue together easily and can be sprinkled with glitter.
