Anytime, or all the time, between Thanksgiving and Christmas is a good time to be decorating a tree. We do it as something of an ongoing project, adding a few more when the inspiration occurs.
Here is a quick and simple ornaments themed lunch which was created with a circle cookie cutter.
In this bento lunch (packed in a Lunchbots quad): A couple of circle shaped sandwiches with Colby Jack cheese accents and a pick. Seedless grapes with an ornament cupcake ring, organic baby carrots, Babybel cheese decorated with some tiny circles topped with an ornament hook pick and sharing its quadrant with pretzels.
