[Cob] Finish on a cob couch

[Amanda Peck]

Clay/sand?  Clay/sand/sawdust? Clay/sand/sawdust/lime putty?  The last of 
those is what I'm chinking with (in approximately 3/7/3/1 ratio)--it comes 
out pretty smooth as you trowel-finish it.  Seal with linseed oil (from your 
local hardware store)?  Don't know how long it will take to dry before you 
can safely put a rug or a mattress on it without getting mold everywhere.

Kim wonders...............

As the cob couch is nearing completion, how it will be finished is coming to
mind--it seems to have boiled down to lime plaster, limewash, or both. The
couch is being built large enough so that it can be used as a bed as well as
for sitting. Anyone here have any ideas as to which would work better?
Thanks.
