Arch made from blocks.

Arch made from small boxes. It includes 6 Girl Scout Cookie boxes, a Cheerios box, and an Oatmeal container steadied by part of a cracker box. I taped a marker to one side of the Girl Scout cookie boxes, to turn each shape from a rectangle into a wedge. The Cheerios box is the keystone.
