As a cereal consuming family, we put at least one to two cereal boxes in the recycle bin each week. Instead of always tossing the containers away, I started creating other uses for them.
If you need to transport cupcakes or muffins and you don't own a cupcake carrier, you can gently put a load of the sweet treats in the box for transport. Just remember which way is up so you don't mess up the frosting.
And, if your child is old enough for a desk, he might enjoy filing boxes for their organizational needs. Just cut the box down to about 3/4 the height all around leaving the top off, too.
Then pick out some crafty printed paper and wrap the box with it. To avoid messes and give the product a nice finished look, use double–stick tape for best results. For the interior of the box, let your child design it using markers or crayons.
Tony the Tiger would think these ideas are GRRReat!
