Fun afterschool snack for kids! Like ants on a log but better: cream cheese + kiwi, peanut butter + blueberries, and more. Try using these snacks in conjunction with children's books like The Snail and the Whale and Charlie the Caterpillar.
This is a perfect combo of my two favorite ideas for that space under the stairs leading to the basement. A reading nook AND book storage and shelves . assuming that there is enough space for this there.
