I finished this shelf back in June with the leftovers from the board that I used for the BiL's valet. I've been trying to put finish on it since then but have been messing up the order and the mix of things. It's finally done now though, after numerous sandings.
It wasn't noticeable before hand, but once I got some finish on it some curl started showing up. It's currently sat near the back door, catching letters, keys and other stuff that I bring to and from the car.
