Step 1 - Measure and cut the battens
In order to find out what sizes to make your rustic wooden shutters, you need to measure the height and width of the windows. The width of the shutters should be about half the the full length of the window. Use the height to calculate the total number of board feet. To save money, my husband purchased 2×12′ lumber boards and we ripped them in half with the table saw.
For this project we used untreated SPF lumber boards. My husband created a cutting jig to attach to the miter saw and marked the various lengths needed on the jig. Our windows turned out to be three different lengths, so this came in handy. Creating the cutting jig meant he had to only measure each length once and that all the battens would be the same lengths as needed.
