[Cob] lime/earth plaster

[Dean Sherwin]

suggest a galvanized construction/expansion joint strip between the two, 
as used in commercial stucco applications to prevent cracking where 
there is a large extent of plaster.  Makes a firm edge and keeps the 
different types separate.
you can caulk the thin gap with flexible matching caulk if the line is a 
problem, but it may also be a good feature
