This first step will help you get a vision of the completed project, and know how much material you will need to buy.
Measure the walls that you want to add shiplap to in order to get an overall length and width of the space.
Use a table saw to rip (or cut) the plywood into 5 inch strips. This creates faux plywood shiplap boards to use for the project.
Start at the bottom of the wall and work your way up to attach the shiplap boards to the wall.
You may need to make additional cuts to fit around obstacles in your space. Things like electrical outlets, light switches, and plumbing can get in the way when you are installing the shiplap.
This trim piece helps to create a finished edge for your shiplap if you are only creating a half wall of shiplap like we did.
Fill any nail holes and then paint the entire shiplap wall.
