I have a moulding style that's my own, and I order it from a supplier that routes out the moulding from my knife. I order it in raw wood that I then stain. A number of the pieces (they are all 7' or longer) have nasty looking knots and/or bad spots right in the middle of the sticks. Is this to be expected? To my way of thinking I'm paying for good quality sticks that should be completely and totally useable, but that's not what I'm getting.
