Wooden Window Shutters?

I am in the process of finally moving my bedroom to the lower level of my home (kids are getting older). I am going with an Adirondack Log Cabin look. I have been collecting things over the years for the project. I am now ready to start painting. I have 1 huge garden window, 1 picture window, and 4 other big windows plus a fireplace with brick all the way up to the ceiling in the middle of the 4 side windows.

So I have a lot of windows to cover.

I would like to make or purchase wooden window shutters that will bi-fold when opening or closing. I would love any input that someone could give me, I'm stumped on this one. I'd like to make them. I've had no luck trying to find them online, at least not what I'm looking for, or I'm not looking in the right place.

Thanks!
