i think he just did it for the look. i just got some plain ol' treated 10 foot 2x4s and cut them in half with a hack saw. i've got some compliments on it, and then they're less impressed when they realize how simple it is, lol. i tell them they should be more impressed by the simplicity.Nice, simple idea......I think I am going to give this one a shot. In the pictures, it looks like the 2x4's are cut in half at an angle. Is there a reason that they need to be cut at an angle? Thanks for the input!
