Cardboard with Walnut Base

I like to turn interesting materials.  The cardboard in this bowl came from three ring binder backs.  I used epoxy to laminate the cardboard and Walnut base together and to top coat the bowl once I completed the process.  It is really different, yet, I really like the concrete look with the warmth of the Walnut base.  About 12" wide by 5" tall, signed and numbered.
