construction paper

If I could go back in time, I would definitely invent the construction paper. Imagine how much money I would have now. Its used everyday in almost every kindergarten classroom in the country.

And who thought of creating hats out of construction paper? On my last day in kindergarten, we made april bunny hats (one of my students was a Jehova's Witness) instead of easter bunny hats. Who had the idea of putting a slip of paper around the head and putting it together in a classroom? I wonder.
