[Cob] Bottle walls

[Sharon]

Hi everyone!
Stumbled on this web page yesterday and thought it may be of interest  
to some of you. I know most of the "wall" are made with bottles and  
concrete, but was thinking I would use the idea using cob instead of  
the concrete.
Do you think that will work with cob?

Thank you,
Sharon
