Cork? Really?

Now what are the uses of cork ?
Plug a bottle, pin up notices even  flooring
Who would think to try to make paper with it ?
Well I did , the paper is pretty crisp , maybe you would say brittle
It cannot be folded or cut in a straight edge ,it can be gently torn
and glued to cardstock either in sheet or pieces.
Some cork put in paper pulp may work differently HUMMM another venture
