A hexagonal prism is a geometric solid (but not a Platonic solid) that has eight faces; each end is a hexagon, and the six other faces are rectangles.
Cut out along the edges and decorate the paper. Fold along the inside lines and form into a hexagonal prism shape.
Glue the flaps A and B and secure them in place. Then glue the flaps labeled C to the inside of the prism. Finally, accordion fold the flaps of the other end into a flower-shaped design.
