I have 3 of these louvred doors, one of which is being used for the external cupboard I built earlier. I built the new study shelves around these doors. I don't like the louvres as they are impossible to clean properly. So I removed the louvres with the intention of reusing them as flat slats. I bought some trim, nailed it to the side of the frames and glued the trimmed down louvres. 2 down, one more to go...finishing...keeping with my word for the year.
