I am considering having a friend that builds custom furniture make table toppers for some sub-woofers that match (as closely as reasonable) the natural finish Bamboo speakers.

Where can he order the same or similar sheets of laminated bamboo used to build the speakers?

Also, I remember from reading the story of the Sierra 1's development that bamboo is hard to work with -- literally. Being a physically hard material, is there anything that I should tell my woodworker friend since he hasn't yet worked with the stuff?
