I purchased these great shutters from the McCammon Country Farms vintage shop on Etsy last spring.
I also found some much larger plantation shutters at a local thrift / second hand store. One of them is almost the size of a door (I did not have a chance to do anything with those yet) and one is approximately 5'x2' in size. Here is the before picture:
I also added (glued) fancy wood carving / cutouts on each piece of the shutter (purchased from Michaels).
