I'm from north east Arkansas and I've fell in love with anything cob... We have all kinds of ground around here and where we want to build is almost all sand. My questions are is there anywhere I can buy clay that's not extremely high? My next question is there any contractors in NEA? My husband and I both have full time jobs and a 1 yr old so it's just not hardly possible for us to build it our selves. Any downfalls to these homes would be appreciated also.
