The earthbag house on the alternative housing tour was made with bags but the woman that built it said she it would have been easier if they had used the continuous fill tubes that calearth.com sells. While poking around that site I found a cool article with accompanying pdf on how to build beautiful little dwellings with sandbags, barbed wire and a few hand tools. http://calearth.org/images/pdfs/Khalili-emergency-shelter.pdf
What fun to go out in your back yard, play in the dirt and build a little dwelling. If I wasn’t hiking this year, this is what I would be doing.
