Hoffman is now selling a 220 thread count bleached white PFD cotton lawn that is being hyped as the same base fabric they use for their batiks. I believe that is what the OP is talking about. It is not batik until it's dyed, as has been said, and will have no pattern/design whatsoever. IMO, it will simply look like a plain white sheet, very boring.
