Hi Steve,
My name is Martina and my family has also been thinking of building a straw bale, cob, or earth bag tiny home in Eastern Oklahoma. We're weighing the pros/cons of different sustainable methods that allow for passive heating/cooling and that can handle the humidity. I'm curious to hear how it's been going for you. Perhaps you'd be open to a phone call to chat about it sometime. My email is
coral.puzzle.0b@icloud.com if you want to set something up.
