I'm not sure I'm calling this right thing, or if even there is a proper name for them; but, I saw a picture on the back of a wood working magazine (can't remember which one it was) showing some work a man did using boards he placed in grain feed shoot which really roughed up the boards leaving just the harder grain behind. The boxes he made were gorgeous. Since I don't have a grain mill, or access to one, how can you create this kind of effect without one?
Thanks
