Afternoon picnics in our living room

Easton naps during lunch normally, so we are all kind of trapped inside until he wakes up.  To change things up now and then, the kids will ask to do a picnic in the living room while watching a movie. This became a common summer time activity and one that they ask for daily now for dinner as well.  This works well when Easton is sleeping, but when he is awake food tends to get everywhere.
