Hi Nellon, welcome to the forum. A lot of people go with cedar or white pine, but for my money nothing says "homey" like 100 burned out boat motors lining the perimeter of your abode. Now some guys will say you can cover more ground by using old bike frames, or the south eastern style of using old box springs turned on edge, but true hillbilly "chic" can only be accomplished with old boat motors.
hope this helps...
