cork bark

[Rich13]

can i use cork bark from outside if i heat it wash it and bleach it ? if not where can i buy the cork bark panels from?

if you can find a cork tree in queens, then by all means use it.
things like woods can not be sanitized completely with heat or bleach so its kind of a waste of time trying.
there are a few vendors that you can find in the links who sell cork bark.
