[Cob] plaster over plywood & lathe

[Ocean Liff-Anderson]

Kiko did some earthen-plaster-over-standard-studwall construction  
here at FireWorks.  He likes to put up drywall, then apply the  
earthen plaster directly to the cardboard surface of the drywall...

Seems to have worked pretty well.  Though this is an interior  
application, no exposure to weather.
