One thing I love about making these accordion books is that they typically use paper that would have been thrown into the trash or recycling bin.

The construction paper is also from the scrap box, so I am using as much of what would be tossed as possible.

It allows for experimentation with the concept with little worry about wasted materials or about making mistakes because it is so easy to start over. And the students love making them, sometimes making more than one!
