We decided to tackle this project over a three day weekend. We went a little over but it was well worth it! Completely transformed our living room from a bunch of blank boring walls to an intricate inviting space. Leave a comment if you have any questions. Here is a list of the materials that we used:

4ftx8ft revolution ply plywood (wall paneling)
1x8x10ft whitewood board (baseboards and top trim)
1x3x6ft whitewood board (vertical and horizontal battens)
1x2x8ft whitewood board (top ledge trim)
