[Cob] Finish on a cob couch

[Kim West]

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.
