Recycling art

I know a lot of artist who like to recycle by using the backside of paper with sketches on it to make note paper. I found a handy item to organize this paper into a file book. This item is called a "lever file."
By using a spring loaded lever, a clamp will press down on the paper and hold it firmly in the file book...

Nice and neat, you're ready to make notes and sketch with the paper in a handy book form.
