I used 1/4" MDF to achieve the board and batten look in my upstairs bathroom. The pieces were ripped down to 1&1/4" strips, painted, and attached to the walls with liquid nails and 2" gun nails. I decided to use some of the smaller pieces to add a horizontal section running parallel to the top board for the hooks to line up with. The top ledge is decorative moulding and the base board is 3/4" thick painted MDF.
