[Cob] Finish on a cob couch

[D.J. Henman]

Be careful of the linseed oil.   Don't get the kind that has been 
processing and has had chemicals added to it.   Also the raw pure 
lineseed oil has to be heated before use, I believe I remember.   Please 
research this.   This would give you a earthen color wall.

Hemp oil is also a very good oil to us.   

But, lime is the traditional rendering for earthen walls.
