My experience with the locally available hog wire is that it comes in shorter heights , either 34" or 50". To do a 6 or 7 ft. high fence, you would have to turn it on it's side and then you would need a lot more posts because of your limited width. If you want a 6-7' high economical fence, you could transition to a roll of 6' field wire and stretch it between some nice cedar posts. Good luck with your project.
